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 SSP-100 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 SSP-100 in hexadecimal and must
reside on an even 8-byte boundary.
irq specifies the interrupt level (IRQ) of the SSP-100 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 an SSP-100 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 SSP-100 will not be configured.
5.1.2.1 Example 1
DEVICE=C:\SSP-100\SSP100.SYS (3,100,5)
In example 1, the Client Driver will attempt to configure the SSP-100 as COM3 using
I/O addresses 100-107 hex and IRQ 5. If COM3 already exists, or if the I/O address or
IRQ resources are already in use, the SSP-100 will not be configured. Furthermore,
only one SSP-100 can be installed in this system.
