Software/Driver Installation

Note: A base I/O address of 0, e.g., ISIBaseX=oxo, or omission of these parameters for any card X, disables that particular card.

Miscellaneous:

Device files corresponding to ports on the ISIHP cards are created in the / dev folder. Use ttyMxy for normal ports and cumxy for corresponding callout ports. The letter x is the card number (1–4), and y is the port number, (a–p) for 16-port cards.

Normal ports (ttyM) are configured for dial-in connections. Callout ports (cum) are used for dial-out connections.

To view busy I/O address space on your system, enter: cat /proc/ioports

To view busy IRQs, enter:

cat /proc/interrupts

To load the driver manually, use insmod.

Example: To load two ISI cards configured with base I/O addresses 0x210 and 0x200 and IRQs 5 and 10, enter the following in the destination folder:

insmod isicom ISIBase1=0x210 Irq1=5 ISIBase2=0x200 Irq2=10

To remove the driver manually, enter rmmod isicom. This removes the driver only if no ISI ports are in use.
