Chapter 3—Driver Installation - Linux
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 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.
