QSP-200/300 User's Manual  
 
1 Introduction  
The Quatech QSP-200/300 provides four independent RS-422/485 asynchronous serial  
communications interfaces for systems equipped with PCMCIA Type II and/or Type III  
expansion sockets. The QSP-200/300 is a PCMCIA Type II (5 mm) card and is PCMCIA PC  
Card Standard Specification 2.1 compliant.  
The QSP-200/300's serial ports are implemented using 16C550 Universal Asynchronous  
Receiver/Transmitters (UARTs) which are the recommended communications interface for  
multitasking environments and with applications involving high data transfer rates.  
The QSP-200/300's four serial ports are addressed in a single 32 byte I/O block for simplified  
programming and all four channels share a common interrupt (IRQ). A special interrupt status  
register is also available to simplify the software required to service multiple serial ports in an  
interrupt driven environments.

2 Windows 95/98/ME/2000/NT Installation  
Windows 95/98 maintains a registry of all known hardware installed within the computer. Inside  
this hardware registry Windows 95/98 keeps track of all the computer's resources, such as base  
I/O addresses, IRQ levels, and DMA channels. In the case of a PC Card (PCMCIA) type board,  
Windows 95/98 configures the new hardware using free resources it finds within the hardware  
registry, and updates the registry automatically.  
Windows 95/98 handles the QSP-200/300 as a "parent/child device". The QSP-200/300 is the  
"parent device". Each serial port is a "child device" of this "parent device". To allow easy  
configuration of Quatech's QSP-200/300, two configuration files have been written. These files  
are called "INF" files. The "QSP-200.INF" file describes the resources of the QSP-200/300  
parent device and indicates the number of child devices. There are 4 child COM ports for the  
QSP-200/300. The "MLTPT_SP.INF" file describes the settings for each serial port including  
all the necessary device drivers.  
Windows 95/98 allows changes in the system resources if the default choices are unacceptable.  
But first, allow Windows 95/98 to configure all of the devices. Since the child COM ports are  
dependent on the parent devices resource allocations, the resources can only be modified at the  
parent device. Changing these resources is an easy task described in a later section.

Card and Socket Services software is commercially available from several vendors for most  
desktop and laptop PCs. If you are unsure whether Card and Socket Services software is  
currently installed on your system, install the QSP-200/300 Client Driver as discussed in  
following section. When loaded, the Client Driver will display an error message if Card and  
Socket Services software is not detected.

4.1 QSP-200/300 Client Driver for DOS  
In order to use the QSP-200/300 Client Driver, the system must be configured with Card and  
Socket Services software. Card and Socket Services software is not provided with the  
QSP-200/300.  
IMPORTANT:  
Some versions of Card and Socket Services dated before 1993  
do not support general purpose I/O cards. If after careful  
installation of the Client Driver the QSP-200/300 does not  
configure or operate properly, an updated version of Card and  
Socket Services may be required.  
4.1.1 Client Driver Installation  
The following procedure is used to install the QSP-200/300 Client Driver:  
1. Copy the file QSP200CL.SYS from the QSP-200/300 distribution CD onto the  
system's hard drive.  
2. Using an ASCII text editor, open the system's CONFIG.SYS file located in the root  
directory of the boot drive.  
3. Locate the line(s) in the CONFIG.SYS file where the Card and Socket Services  
software is installed.  
4. AFTER the line(s) installing the Card and Socket Services software, add the  
following line to the CONFIG.SYS file:  
DEVICE = drive:\path\QSP200CL.SYS  
options  
where options are the QSP-200/300 Client Driver command line options  
discussed on the following pages.  
5. Save the CONFIG.SYS file and exit the text editor.  
6. Insert the QSP-200/300 into one of the system's PCMCIA slots.  
NOTE: Since the QSP-200/300 Client Driver supports "Hot Swapping", it is not  
necessary to have the QSP-200/300 installed when booting the system. By inserting  
the card before booting, however, the Client Driver will report the adapter  
configuration during the boot process thereby verifying the changes made to the  
CONFIG.SYS.  
7. Reboot the system and note the message displayed when the QSP-200/300 Client  
Driver is loaded. If the Client Driver reports an "invalid command line option",  
QSP-200/300 User's Manual  
16  
 
correct the entry in the CONFIG.SYS file and reboot the system again. If the Client  
Driver reports "Card and Socket Services not found", a version of Card and Socket  
Services must be installed on the system or the QSP-200/300 Enabler program must  
be used to configure the adapter. If the Client Driver reports the desired adapter  
configuration, the installation process is complete and the QSP-200/300 may be  
removed and / or inserted from the system as desired. On each insertion into the  
PCMCIA socket, the QSP-200/300 will be automatically reconfigured according to  
the command line options.  
4.1.2 Command Line Options  
The QSP-200/300 Client Driver accepts up to eight command line arguments from the user to  
determine the configuration of the QSP-200/300. If any arguments are provided, the Client  
Driver will attempt to configure any QSP-200/300s with the options specified in the order they  
are entered on the command line. Each argument must be enclosed in parenthesis and must be  
separated from other arguments by a space on the command line. Within each argument, any or  
all of the following parameters may be specified using a comma (no spaces) to separate each  
parameter:  
Baddress specifies the base I/O address of the QSP-200/300 in hexadecimal and must reside  
on an even 32-byte (20H) boundary. If this option is omitted, a base address will be  
assigned by Card and Socket Services.  
Iirq  
specifies the interrupt level (IRQ) of the QSP-200/300 in decimal. irq must be one  
of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is desired. If  
this option is omitted, an interrupt level will be assigned by Card and Socket  
Services.  
Ssocket  
Omode  
specifies which PCMCIA socket the QSP-200/300 must be inserted into for this  
configuration argument to be used. socket must be in the range 0 - 15. If this option  
is omitted, the configuration argument will apply to QSP-200/300s inserted into any  
socket.  
specifies RS-422/485 output driver mode. The QSP-200/300’s ports may be  
configured for either full duplex or half duplex operation with this option. If this  
option is omitted, the default setting is the RS-422/485 ports are configured for full  
duplex operation with the RS-422/485 output drivers always enabled. In half duplex  
mode, the RS-422/485 transmitter may be enabled and disabled via the RTS (request  
to send) or DTR (data terminal ready) signals. Both RTS and DTR are controlled  
through the Modem Control Register of the 16550. See the Hardware Information  
section for more information.

H
instructs the client driver to enable the RTS-CTS modem control handshake. When  
modem control handshaking in enabled, the 16C550 UART’s RTS and CTS signals  
are connected to the RS-422/485 auxiliary channel (AuxOut and AuxIn). The  
auxiliary channel may then be used for handshaking between a DSP-200/300  
RS-422/485 port and a peripheral device. When modem control handshaking is  
disabled, the RTS and CTS signals from the 16C550 UART are looped back to each  
other. If this option is omitted, the default setting is RTS-CTS modem control  
handshake disabled. See the Hardware Information section for more information.  
U
instructs the Client Driver to disable the QSP-200/300's interrupt status register and  
enable the Scratchpad registers of the individual UARTs. This option is only  
required in very rare cases where an application program requires access to the  
UART's Scratchpad register. If this option is omitted, the QSP-200/300's interrupt  
status register is enabled and the UARTs' Scratchpad registers are disabled.

4.1.3 QSP-200/300 Client Driver Examples  
Example 1  
DEVICE = C:\QSP-200\QSP200CL.SYS  
In example 1, no command line arguments are specified. The Client Driver will configure a  
QSP-200/300 inserted into any socket with a base address and IRQ assigned by Card and Socket  
Services. The output drivers will be configured for full duplex operation (always enabled), the  
RTS-CTS handshaking will be disabled (loopback mode), and the interrupt status register will be  
enabled.  
Example 2  
DEVICE = C:\QSP-200\QSP200CL.SYS (b300)  
In example 2, a single command line argument is provided. The Client Driver will attempt to  
configure a QSP-200/300 inserted into any socket with a base address of 300H and an IRQ  
assigned by Card and Socket Services. If address 300H is unavailable, the QSP-200/300 will not  
be configured. If the Client Driver can successfully configure the card, the output drivers will be  
configured for full duplex operation (always enabled), the RTS-CTS handshaking will be  
disabled (loopback mode), and the interrupt status register will be enabled.  
Example 3  
DEVICE = C:\QSP-200\QSP200CL.SYS (s0,b300,i5)  
In example 3, a single command line argument is provided. The Client Driver will attempt to  
configure a QSP-200/300 inserted into socket 0 with a base address of 300H and IRQ 5. If  
address 300H or IRQ 5 is unavailable, the card will not be configured. In addition, if a  
QSP-200/300 is inserted into any other socket, it will not be configured. If the Client Driver can  
successfully configure the card, the output drivers will be configured for full duplex operation  
(always enabled), the RTS-CTS handshaking will be disabled (loopback mode), and the interrupt  
status register will be enabled.  
QSP-200/300 User's Manual  
19  
 
Example 4  
DEVICE = C:\QSP-200\QSP200CL.SYS (i5,h,u,b300,o2)  
In example 4, a single command line argument is provided. Because the parameter order is not  
significant, the Client Driver will attempt to configure a QSP-200/300 inserted into any socket  
with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the card will  
not be configured. If the Client Driver can successfully configure the card, the output drivers  
will be configured for RTS controlled half duplex operation, the RTS-CTS handshaking will be  
enabled, and the interrupt status register will be disabled (i.e. the UARTs' Scratchpad registers  
will be enabled).  
Example 5  
DEVICE = C:\QSP-200\QSP200CL.SYS (b300,i5) (i10) ( )  
In example 5, three command line arguments are provided. The Client Driver will first attempt  
to configure a QSP-200/300 inserted into any socket with a base address of 300H and IRQ 5. If  
address 300H or IRQ 5 is unavailable, the Client Driver will proceed to the second command line  
argument and attempt to configure the card with a base address assigned by Card and Socket  
Services and IRQ 10. If IRQ 10 is also unavailable, the Client Driver will proceed to the third  
command line argument and attempt to configure the card with a base address and an IRQ  
assigned by Card and Socket Services. If the Client Driver can successfully configure the card,  
the output drivers will be configured for full duplex operation (always enabled), the RTS-CTS  
handshaking will be disabled (loopback mode), and the interrupt status register will be enabled.  
QSP-200/300 User's Manual  
20  
 
Example 6  
DEVICE = C:\QSP-200\QSP200CL.SYS (b300,i5) ( ) (i10)  
In example 6, the three command line arguments of example 5 have been rearranged. The Client  
Driver will first attempt to configure a QSP-200/300 inserted into any socket with a base address  
of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the Client Driver will proceed to  
the second command line argument and attempt to configure the card with a base address and  
IRQ assigned by Card and Socket Services. Since the second command line argument includes  
all available address and IRQ resources, the third command line argument will never be reached  
by the Client Driver. It is the user's responsibility to place the command line arguments in a  
logical order.  
Example 7  
DEVICE = C:\QSP-200\QSP200CL.SYS (s0,b300,i5) (s1,b340,i10,o1)  
The type of configuration shown in example 7 may be desirable in systems where more than one  
QSP-200/300 is to be installed. In this example, the Client Driver will attempt to configure a  
QSP-200/300 inserted into socket 0 with a base address of 300H and IRQ 5. If the card is  
inserted into socket 1, the Client Driver will attempt to configure it with base address 340H and  
IRQ 10. This allows the user to force the address and IRQ settings to be socket specific which  
may simplify cable connections and software development. As in the previous examples,  
however, if the requested address or interrupt resources are not available, the QSP-200/300 will  
not be configured.  
QSP-200/300 User's Manual

4.1.4 Common Problems  
Generic Client Drivers:  
Many Card and Socket Services packages include a generic client driver (or "Super Client")  
which configures standard I/O devices. If one of these generic client drivers is installed, it may  
configure the QSP-200/300 causing the QSP-200/300 client driver to fail installation. In these  
cases, the user should do one of the following:  
1. modify the operation of the generic client driver to disable the configuration of  
modem/serial port cards. Consult the Card and Socket Services documentation for  
availability and details of this feature.  
2. place the QSP-200/300 client driver before the generic client driver in the  
CONFIG.SYS.  
Available Resources:  
One function of the Card and Socket Services software is to track which system resources  
(memory addresses, I/O addresses, IRQs, etc.) are available for assignment to inserted PCMCIA  
cards. Sometimes, however, the Card Services software assumes or incorrectly determines that a  
particular resource is used when it is actually available. Most Card and Socket Services generate  
a resource table in a file (typically in the form of an .INI file) which the user can modify to adjust  
the available system resources. Consult the Card and Socket Services documentation for  
availability and details of this feature.  
Multiple Configuration Attempts:  
Some Card and Socket Services have a setting which aborts the configuration process after a  
single configuration failure (such as a request for an unavailable resource). The user should  
change this setting to allow for multiple configuration attempts. Consult the Card and Socket  
Services documentation for availability and details of this feature.  
Older Versions of Card and Socket Services:  
Some versions of Card and Socket Services dated before 1993 do not support general purpose  
I/O cards. If after careful installation of the Client Driver the QSP-200/300 does not configure or  
operate properly, an updated version of Card and Socket Services may be required. Card and  
Socket Services software is available from Quatech Inc.  
4.2 QSP-200/300 Enabler for DOS  
For systems that are not operating PCMCIA Card and Socket Services software, the  
QSP-200/300 DOS Enabler may be used to enable and configure the adapter. This Enabler,  
QSP200EN.EXE, will operate on any DOS system using an Intel82365SL or PCIC compatible  
PCMCIA host adapter including the Cirrus Logic CL-PD6710 / 6720, the VLSI VL82C146, and  
the Vadem VG-365 among others.  
QSP-200/300 User's Manual  
22  
 
IMPORTANT:  
In order to use the QSP-200/300 Enabler for DOS, the system  
MUST NOT be configured with Card and Socket Services  
software. If a Card and Socket Services software is installed, the  
QSP-200/300 Enabler may interfere with its operation and with the  
device(s) it controls.  
The QSP-200/300 Enabler does not support automatic configuration of adapters upon insertion,  
more commonly referred to as "Hot Swapping". This means the adapter must be installed in one  
of the system's PCMCIA sockets before executing QSP200EN.EXE. If more than one adapter is  
installed in a system, the Enabler must be executed separately for each adapter. Furthermore,  
QSP200EN.EXE should be executed to release the resources used by the adapter before it is  
removed from the PCMCIA socket. Since PCMCIA adapters do not retain their configuration  
after removal, any adapter that is removed from the system must be reconfigured with the  
Enabler after reinserting it into a PCMCIA socket.  
IMPORTANT:  
The Enabler requires a region of high DOS memory when configuring  
a QSP-200/300. This region is 1000H bytes (4KB) long and by  
default begins at address D0000H (the default address may be changed  
using the "W" option). If a memory manager such asEMM386,  
QEMM, or 386Max is installed on the system, this region of DOS  
memory must be excluded from the memory manager's control.  
Consult the documentation provided with the memory manager  
software for instructions on how to exclude this memory region.  
QSP-200/300 User's Manual  
23  
 
4.2.1 Command Line Options  
To configure a QSP-200/300 in the system, the Enabler requires one command line argument  
from the user to determine the configuration of the card. This argument must be enclosed in  
parenthesis and within the argument, any or all of the following parameters may be specified  
using a comma (no spaces) to separate each parameter:  
Ssocket  
specifies which PCMCIA socket the QSP-200/300 must be inserted into for this  
configuration argument to be used. socket must be in the range 0 - 15. This option is  
always required.  
Baddress specifies the base I/O address of the QSP-200/300 in hexadecimal and must reside  
on an even 32-byte (20H) boundary. This option is required if the 'R' option is not  
used.  
Iirq  
specifies the interrupt level (IRQ) of the QSP-200/300 in decimal. irq must be one  
of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is desired.  
This option is required if the 'R' option is not used.  
Waddress specifies the base address of the memory window required to configure the  
QSP-200/300. Set address = D0 for a memory window at segment D000, address =  
D8 for a memory window at segment D800, etc. Valid settings for address are C8,  
CC, D0, D4, D8, and DC. If this option is omitted, a memory window at segment  
D000 will be used.  
Omode  
specifies RS-422/485 output driver mode. The QSP-200/300’s ports may be  
configured for either full duplex or half duplex operation with this option. If this  
option is omitted, the default setting is the RS-422/485 ports are configured for full  
duplex operation with the RS-422/485 output drivers always enabled. In half duplex  
mode, the RS-422/485 transmitter may be enabled and disabled via the RTS (request  
to send) or DTR (data terminal ready) signals. Both RTS and DTR are controlled  
through the Modem Control Register of the 16550. See the Hardware Information  
section for more information.

RS-422/485 port and a peripheral device. When modem control handshaking is  
disabled, the RTS and CTS signals from the 16C550 UART are looped back to each

other. If this option is omitted, the default setting is RTS-CTS modem control  
handshake disabled. See the Hardware Information section for more information.  
U
instructs the Enabler to disable the QSP-200/300's interrupt status register and enable  
the Scratchpad registers of the individual UARTs. This option is only required in  
very rare cases where an application program requires access to theUART's  
Scratchpad register. If this option is omitted, the QSP-200/300's interrupt status  
register is enabled and the UARTs' Scratchpad registers are disabled.  
Before removing a QSP-200/300 from its PCMCIA socket, the Enabler should be executed to  
free the system resources allocated when the card was installed. For this operation the Enabler  
provides on additional command line option:  
R
instructs the Enabler to release the resources previously allocated to the  
QSP-200/300. When the 'R' option is used, any settings specified by the 'B', 'I', 'U',  
and 'E' options are ignored. This option must be omitted when installing a  
QSP-200/300 into the system.

QSP200EN.EXE  
In example 1, no command line argument is specified. The Enabler will report an error and  
display the proper usage of the command.  
Example 2  
QSP200EN.EXE (s0,b300,i5)  
In example 2, the Enabler will configure the QSP-200/300 in socket 0 with a base address of  
300H and IRQ 5 using a configuration memory window at segment D000. The output drivers  
will be configured for full duplex operation (always enabled), the RTS-CTS handshaking will be  
disabled (loopback mode), and the interrupt status register will be enabled.  
Example 3  
QSP200EN.EXE (i10,u,b340,s1,o1,h)  
In example 3, the Enabler will configure the QSP-200/300 in socket 1 with a base address of  
340H and IRQ 10 using a configuration memory window at segment D000. The output drivers  
will be configured for DTR controlled half duplex operation, the RTS-CTS handshaking will be  
enabled, and the UARTs' Scratchpad registers will be enabled (i.e. the interrupt status register  
will be disabled). Note that the parameter order is not significant.  
Example 4  
QSP200EN.EXE (s0,b300,i3,wd8)  
In example 4, the Enabler will configure the QSP-200/300 in socket 0 with a base address of  
300H and IRQ 3 using a configuration memory window at segment D800. The output drivers  
will be configured for full duplex operation (always enabled), the RTS-CTS handshaking will be  
disabled (loopback mode), and the interrupt status register will be enabled.

4.2.3 Common Problems  
Memory Range Exclusion:  
The Enabler requires a region of high DOS memory when configuring a QSP-200/300. This  
region is 1000H bytes (4KB) long and by default begins at address D0000H (the default address  
may be changed using the "W" option). If a memory manager such asEMM386, QEMM, or  
386Max is installed on the system, this region of DOS memory must be excluded from the  
memory manager's control. Consult the documentation provided with the memory manager  
software for instructions on how to exclude this memory region.  
Furthermore, some systems use the high memory area for BIOS shadowing to improve overall  
system performance. In order for the Enabler to operate, any BIOS shadowing must be disabled  
in the address range specified for the configuration window. BIOS shadowing can usually be  
disabled through the system's CMOS setup utility.  
Contention with Other Devices:  
Without Card and Socket Services support, the QSP-200/300 Enabler has no way to determine  
the resources in use by other devices in the system. It is the user's responsibility to guarantee that  
the parameters specified on the Enabler command line are available in the system and will not  
cause a conflict.  
Socket Numbers:  
The Enabler requires the QSP-200/300's socket number to be specified on the command line and  
the card must be inserted into the socket before the Enabler is invoked. Some vendors number  
their sockets from 1 to N while other vendors number their sockets from 0 to N-1. For the  
QSP-200/300 Enabler, the lowest socket number in the system is designated socket 0.  
Card and Socket Services Software:  
In order to use the QSP-200/300 Enabler for DOS, the system MUST NOT be configured with  
Card and Socket Services software. If a Card and Socket Services software is installed, the  
QSP-200/300 Enabler may interfere with its operation and with the device(s) it controls. For  
systems configured with Card and Socket Services, the QSP-200/300 Client Driver is the  
recommended method of configuration.  
QSP-200/300 User's Manual

5 OS/2 Installation  
In order to use the QSP-200/300 Client Driver for OS/2, the system must be configured as  
follows:  
1. The system must be running OS/2 2.1 or later.  
2. OS/2 PCMCIA Card and Socket Services support must be installed. If PCMCIA  
support was not selected when OS/2 was installed, it can be added using the Selective  
Install facility in the System Setup folder. On OS/2 2.1 and 2.11, Socket Services  
must be added separately. The necessary files can be found onCompuserve in the  
OS2SUPPORT forum and may be available elsewhere. These files are not available  
from Quatech Inc.  
3. Quatech's OS/2 serial port device driver, "QCOM" version 2.01 or later, must be  
installed. The QSP-200/300 will not operate with the standard OS/2 serial port device  
drivers. Quatech Inc. can not guarantee the operation of the QSP-200/300 with any  
other third party device drivers for OS/2.  
4. There must be at least 32 bytes of available I/O space and 1 availableIRQ.  
After the system has been configured to the above specifications, the QSP-200/300 Client Driver  
may be installed with the following procedure:  
1. Copy the QSP200.SYS client driver file from the Quatech COM CD to any  
convenient directory on the hard disk.  
2. Open the CONFIG.SYS file using any ASCII text editor.  
3. Add the following line to the CONFIG.SYS file:  
DEVICE =  
drive:\path\QSP200.SYS options  
where options are the QSP-200/300 OS/2 Client  
Driver command line options discussed in the following sections.  
4. Save the CONFIG.SYS file, exit the text editor, shutdown the system, and reboot to  
activate the changes.

5.1 Command Line Options  
The QSP-200/300 Client Driver for OS/2 supports two methods of configuration: using "system  
assigned" resources and using "user assigned" resources. Both options provide fullPCMCIA  
compliance and functionality (including "Hot-swapping") but each has some advantages and  
disadvantages as discussed in the following sections.  
5.1.1 Configuring With "System Assigned" Resources  
Allowing the OS/2 Plug-and-Play system to assign the hardware resources to the QSP-200/300 is  
the ideal choice when only OS/2 programs will access the serial ports. When configuring the  
hardware, the user simply specifies a list of COM port numbers. When a QSP-200/300 is  
inserted into a PCMCIA socket, the client driver will configure the card as a series of COM  
ports, starting with the lowest available port number in the list.  
Configuring a QSP-200/300 with system assigned resources can be a problem, however, if DOS  
and/or Windows applications will be accessing the serial ports. This is because most DOS  
applications write directly to the communications hardware and the Windows' Control Panel also  
wants to know the hardware configuration of the serial ports. In these cases, the user may want  
to configure the QSP-200/300 with "user assigned" resources.  
Example 1  
DEVICE=C:\QSP-200\QSP200.SYS COM3  
In example 1, the Client Driver will attempt to configure the QSP-200/300 as COM3 through  
COM6. If COM3, 4, 5, or 6 already exists in the system, the QSP-200/300 will not be  
configured. Furthermore, only one QSP-200/300 can be installed in this system.  
Example 2  
DEVICE=C:\QSP-200\QSP200.SYS COM7 COM3  
In example 2, the Client Driver will attempt to configure the QSP-200/300 as COM3 through  
COM6. If COM3, 4, 5, or 6 already exists in the system, the Client Driver will attempt to  
configure the QSP-200/300 as COM7 through COM10. If COM7, 8, 9, or 10 already exist in the  
system, the QSP-200/300 will not be configured. Up to two QSP-200/300s can be installed in  
this system.

5.1.2 Configuring With "User Assigned" Resources  
As mentioned in the previous section, allowing the OS/2 Plug-and-Play system to assign the  
hardware resources to the QSP-200/300 is ideal for OS/2 programs but can be a problem if DOS  
and/or Windows applications will be accessing the serial ports. This is because most DOS  
applications write directly to the communications hardware and the Windows' Control Panel also  
wants to know the hardware configuration of the serial ports. For this reason, the QSP-200/300  
Client Driver allows the user to request specific hardware settings using a series of command line  
arguments of the form  
(port,address,irq)  
port  
specifies the beginning COM port number  
address specifies the base I/O address of the QSP-200/300 in hexadecimal and must reside  
on an even 32-byte (20H) boundary.  
irq  
specifies the interrupt level (IRQ) of the QSP-200/300 in decimal. irq must be one  
of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, or 15.  
Each argument must be enclosed in parentheses and must be separated from other arguments by a  
space on the command line. Within each argument, the parameters must be separated using a  
comma (no spaces).  
When a QSP-200/300 is inserted into a PCMCIA socket, the client driver will configure the card  
as a series of COM ports, starting with the lowest available port number in the list.  
IMPORTANT:  
If the user specified resources are in-use by other devices in the  
system, the QSP-200/300 will not be configured.  
Example 1  
DEVICE=C:\QSP-200\QSP200.SYS (3,100,5)  
In example 1, the Client Driver will attempt to configure the QSP-200/300 as COM3 through  
COM6 using I/O addresses 100-11F hex and IRQ 5. If COM3, 4, 5, or 6 already exists, or if the  
I/O address or IRQ resources are already in use, the QSP-200/300 will not be configured.  
Furthermore, only one QSP-200/300 can be installed in this system.  
QSP-200/300 User's Manual  
31  
 
Example 2  
DEVICE=C:\QSP-200\QSP200.SYS (7,120,15) (3,300,4)  
In example 2, the Client Driver will attempt to configure the QSP-200/300 as COM3 through  
COM6 using I/O address 300-31F hex and IRQ 4. If COM3, 4, 5, or 6 already exists, or if the  
I/O address or IRQ resources are already in use, the Client Driver will attempt to configure the  
QSP-200/300 as COM7 through COM10 using I/O address 120-13F hex and IRQ 15. If COM7,  
8, 9, or 10 already exists or if the I/O address or IRQ resources are already in use, the  
QSP-200/300 will not be configured. Up to two QSP-200/300s can be installed in this system.  
5.1.3 Advanced Configuration Topics  
For some applications, it may be desirable to specify the resources for one QSP-200/300 while  
allowing the OS/2 Plug-and-Play system to assign the hardware resources for any additional  
cards. This can be accomplished by mixing the configuration methods on the QSP-200/300  
Client Driver command line  
DEVICE=C:\QSP-200\QSP200.SYS (3,100,5) COM7  
It is important to remember that when a QSP-200/300 is inserted into a PCMCIA socket, the  
client driver will configure the card as a series of COM ports, starting with the lowest available  
port number in the list.  
Another common application requirement is to have a QSP-200/300 inserted into socket 1 be  
configured as COM3 through COM6 while a QSP-200/300 inserted into socket 2 be configured  
as COM7 through COM10. This type of configuration is supported by appending a "=Sx"  
parameter after any command line argument.  
DEVICE=C:\QSP-200\QSP200.SYS COM3=S1 COM7=S2  
DEVICE=C:\QSP-200\QSP200.SYS (3,100,4)=S1 (7,300,3)=S2

5.2 Monitoring The Status Of PCMCIA Cards  
OS/2 Warp provides a utility called "Plug and Play for PCMCIA" that can be used to monitor the  
status of each PCMCIA socket. In OS/2 2.1, this utility is called "Configuration Manager".  
When a QSP-200/300 is inserted, the Card Type for the appropriate socket will display  
"Multi-Function". If the card is successfully configured, the Card Status will display "Ready". If  
the card cannot be configured, the Card Status will be "Not Ready". You can view the  
resources claimed by a configured card by double-clicking on that card's line in the window.

5.3 Common Problems  
Invalid I/O Address When Using OS/2 2.1:  
PCMCIA Card Services for OS/2 2.1 sometimes fails to supply a valid I/O address when using  
"system assigned" resources. Use the "Configuration Manager" program to examine the I/O  
address range assigned to the QSP-200/300. If this range does not begin on an even 32 byte  
(20H) boundary, the QSP-200/300 will have to be installed using "user assigned" resources to  
force a valid configuration.  
There have not been any reports of this problem with OS/2 Warp.  
Resources Not Available:  
When using "user assigned" resources, it is the user's responsibility to ensure the I/O address and  
IRQ resources are available. For OS/2 Warp users, the RMVIEW utility may be useful in finding  
resource conflicts. Type "rmview /?" at an OS/2 command prompt for details.  
When using "system assigned" resources, if the user knows the port number is available then the  
system may not have sufficient resources available to configure the QSP-200/300. Again, the  
RMVIEW utility provided with OS/2 Warp may be useful in determining the problem.  
Regardless of the configuration method, each command line argument specifies the first of four  
COM ports for the QSP-200/300. If any of these COM ports are already installed, the Client  
Driver will not load.  
Parameter Overlapping:  
When installing the QSP-200/300, each command line argument specifies the first of four COM  
ports. If these arguments overlap, the Client Driver will not load. For example, it is illegal to  
specify QSP200.SYS COM3 COM4 because the first argument requests COM3 - COM6 and the  
second argument specifies COM4 - COM7.  
Insufficient Number Of Command Line Arguments:  
The QSP-200/300 command line must contain at least one command line argument for each  
QSP-200/300 to be installed.

6 Hardware Information  
6.1 Port Addressing  
The QSP-200/300's four asynchronous serial ports are implemented using 4 standard 16C550  
UARTs. Each of these UARTs requires 8 bytes of I/O space and when enabled which requires  
the QSP-200/300 to be located on an even 32-byte (20H) boundary (e.g. 300H, 320H, 340H,  
etc.).

6.2 Scratchpad / Interrupt Status Register  
Each 16C550 UART contains 8 I/O registers. The last of these registers, located at (Base address  
+ 7), is referred to as the 'Scratchpad Register' and provides no functionality to theUART. In  
place of this Scratchpad Register, the QSP-200/300 implements an interrupt status register which  
can be accessed at (Base address + 7) of anyUART. The purpose of the interrupt status register  
is to give the software programmer an easy way to inspect the interrupt state of the entire  
QSP-200/300 with a single input operation. The format of the interrupt status register is shown  
below:  
D7  
0
D6  
0
D5  
0
D4  
0
D3  
D2  
D1  
D0  
Intr D Intr C Intr B Intr A  
When one or more UARTs have interrupts pending, the associated bit(s) in the interrupt status  
register are set to logic 1. When all the pending interrupts have been serviced for a specific  
UART, its interrupt status bit will be cleared to logic 0 automatically. When all the pending  
interrupts from all UARTs have been serviced, the entire interrupt status register will return logic  
0. The application program should not exit its interrupt service routine until all pending  
interrupts from all channels have been serviced (interrupt status register = 0) or no additional  
interrupts will be received.  
If an application requires the UARTs' Scratchpad Registers, the interrupt status register can be  
disabled. Disabling the interrupt status register is supported by the QSP-200/300 configuration  
software, which is operating system dependent. Refer to the relevant operating system  
installation section for specific usage of this feature.

6.3 Auxiliary Channel Configuration  
An auxiliary channel is provided which allows for handshaking between a QSP-200/300  
RS-422/485 port and a peripheral device. This auxiliary channel may be configured in one of  
two ways:  
; RTS-CTS handshake enabled.  
; handshaking is disabled.  
All ports must be configured in the same manner.  
6.3.1 Auxiliary Channel: RTS-CTS Handshaking  
The RTS-CTS handshake may be enabled so that RTS (Request To Send) is the auxiliary output  
signal on AuxOut+ and AuxOut- (pins 1 and 6 of the D9 female connector). Similarly, CTS  
(Clear To Send) is the auxiliary input signal on AuxIn+ and AuxIn- (pins 5 and 9 of the D9  
female connector). This configuration is shown below.

6.3.2 Auxiliary Channel: Handshaking Disabled  
The QSP-200/300 ports may be configured so that the RTS-CTS handshake is disabled. This is  
the default configuration. In this configuration, RTS and CTS from the 16C550 UART will be  
looped back to each other. In addition, the auxiliary output and input signals will be looped back  
to each other. This configuration is shown below:

6.4 Termination Resistors  
No termination resistors are provided on the QSP-200/300 ports. Both output and input signals  
are connected only to the external connector. Any termination which is required must be added  
externally.

6.5 2-Wire Operation  
The QSP-200/300’s ports may be configured for either full duplex or half duplex operation. By  
default, the RS-422/485 ports are configured for full duplex operation with the RS-422/485  
output drivers always enabled.  
In half duplex mode, the RS-422/485 transmitter may be enabled and disabled via the RTS  
(request to send) or DTR (data terminal ready) signals. Both RTS and DTR are controlled  
through the Modem Control Register of the 16550.

One of these three options must be selected via

the default mode.  
NOTE:  
Figure 8. RS-422/485 Driver Enable Options  
If RTS is selected as the signal to enable the output drivers, setting 'bit 1' of the Modem Control  
Register (to logic '1') will enable the output drivers and clearing 'bit 1' of the Modem Control  
Register (to logic '0') will force the outputs into a high impedance state.  
Similarly, if DTR is chosen as the signal to enable the output drivers setting 'bit 0' of the Modem  
Control Register (to logic '1') will enable the output drivers and clearing 'bit 0' of the Modem  
Control Register (to logic '0') will force the outputs into a high impedance state.  
Selection of half duplex mode operation is dependent upon the configuration software and/or the  
operating system used. Each of these,  
however, ultimately control the half duplex mode by accessing the PCMCIA Configuration  
Register on the QSP-200/300.  
CAUTION:  
When operating in half duplex mode, the transmitter output drivers  
must be disabled before receiving and information. Failure to do so  
will result in two output drivers being connected together which  
may cause damage to the adapter, the computer, and/or the  
peripheral equipment.
