LINUX -- PPP setup:
The 'PPP-HOWTO' (a document that is available as a part of the 'HOWTO' documentation on most of the
distributions under /usr/doc/HOWTO) explains in detail the procedure for configuring a Linux machine as a PPP
server. This information is also available at
http://www.interweft.com.au/other/ppp-howto/ppp-howto.html.
The documentation in the PPP-HOWTO is directly applicable to ISI ports.
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 ISI3334 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 (14), and y is the port number, (ap) 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.
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 ISI3334 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.
rm ttyM1*
rm ttyM2*
rm ttyM3*
rm ttyM4*
