Multi-Tech Systems ISIHP-2U - Manual (Page 69)

Software/Driver Installation
MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD 69
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.
