First of all, thanks to those who have helped me so far. I am a newbie as
we all were once so I am sure you realize how much the help from all you
Guru's is appreciated.
I am trying to configure an internal Askey 56k (x2) modem. I was told to
check the IRQ and port settings. My IRQ's are this:
0: 32140 timer
1: 388 keyboard
2: 0 cascade
3: 17 aic7xxx
4: 1 + rtc
12: 0 PS/2 mouse
13: 1 math error
14: 20768 + ide0
15: 0 + ide1
I understand the timer, keyboard, cascade, PS/2 mouse and I think the ide0
and 1 are the two hard drives. I don't know what 17 aic7xxx is but I think
it is our SCSI adapter. We also have a Kingston NIC and a Seagate tape
drive which I will also need to configure. I also want to RAID (mirror)
the two hard drives but first things first so back to the modem.
Obviously I have a lot of IRQ's to choose from but I didn't want to pick
one for the modem if one of the above says it already sees the modem. Does
it?
My IO port readings are as follows:
0000-001f : dma1
0020-001f : pic1
0040-005f : timer
0040-006f : keyboard
0070-007f : rtc
00a0-00bf : pic2
00c0-00df : dma2
00f0-00ff : npu
0170-0177 : ide1
01f0-17f7 : ide0
02f8-02ff : serial (auto)
0376-0376 : ide1
03c0-03df : vga+
03f0-03f5 : floppy
03f6-03f6 : ide0
03f7-03f7 : floppy DIR
e800-e8be : aic7xxx
f000-f007 : IDE DMA
f008-f00f : IDE DMA
My question here is, how can I tell from the above which COM ports are
being used? Once I know that I can ln -s /dev/cauX/dev/modem where X is 0
if it is COM 1 and 1 if it is COM 2. Then I can do cu -l/dev/modem -s
38400. From there I am going to use UUCP for connection to another UNIX
box. I used RPM to install that and my books tell me how to write the
scripts for it.
Thanks in advance,
Marshall
