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.
