Multi-Tech Systems ISI5634PCI/4/8 manual Miscellaneous, Removing the ISI Driver Linux

ISI5634PCI/4/8 User Guide

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 ISI5634PCI 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–d) for 4-port cards or (a-h) for 8-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.

Removing the ISI Driver (Linux)

1.Type cd /usr/local. Press ENTER.

2.Type rm -r ISICOM. Press ENTER.

3.This will remove driver for all ISI5634PCI cards in that Linux server.

4.Remove the isictl file by typing “rm isictl” in the /dev directory.

5.Remove all devices that start with ttyM1x, ttyM2x, ttyM3x and ttyM4x in the /dev directory.
