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.
