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.
