POST INSTALLATION:
I. Log into your "Root" account.
II. To determine resource settings.
Type the following command: cat /proc/pci
An example of the outcome will look like this;
5. Non-prefetchable
32 bit memory at 0x00000000.
Bus 0, device 17, function 0:
Communication controller: Unknown vendor
Unknown device (rev 0).
Vendor id=11c1. Device id=480.
Medium devsel. Fast back-to-back
capable. IRQ 11. Master Capable.
No bursts.
Min
Gnt=252.Max Lat=14
Non-prefetchable
32 bit memory at 0xe4000000.
I/O at 0x6400.
I/O at 0x6800.
I/O at 0x6c00.
III. Take note of the IRQ, and FIRST I/O address, then type in this command;
setserial /dev/modem uart 16550A port 0x6400 irq 11
NOTE: THE IRQ AND PORT MAY VARY, IT IS DEPENDANT UPON THE RESULTS FROM STEP II
IV. To set Linux to configure the modem upon boot-up.
There are several options. One method is going to the /etc/rc.d/
directory, and using an editing program such as "jed" or
"pico" edit the
rc.local file, and insert
setserial /dev/modem uart 16550A port 0x6400 irq 11
as the last line.
