Very Computer

I've seen messages w/ issues similar to mine, but their answers doesn't
include what I need.  Well, this is my problem...

I have an internal modem, winmodem, which I used in another machine
running RH Linux for the last two years w/out a hitch.  Now I'm setting
a small network at home, and the modem card was moved to another machine
also running Linux.  The problem is that I cannot get a hold of it.  I
know that the card under Win95 has the following setup:

Port:        COM4
Interrupt:  3
I/O Add.: 0x2E8
UART:    16550

Thus, I set up the card in the Linux machine as:

Port:        /dev/cua3
Interrupt:  3
I/O Add.: 0x2E8
UART:    16550

I ran "procinfo" before and after I installed the card to be able to
identify the interrupt and i/o address, and was able to see the modem
using the correct i/o address, but not the interrupt.  According to
"procinfo," no device is using IRQ 3.  Not even the modem, which is
setup w/ this IRQ.  I tried using minicom to give a try to the setup,
and no matter what I tried nothing happens; I cannot even hear the click
of the relays on the modem card.  And yes, I did initialized the card
correctly. Any suggestions?  Thanks!

You might try using setserial and do a manual config.  It's actually
healthier for the system this way.  Good Luck!

That's how I configured the port under Linux.  Didn't work!  There is
something else there!  Thanks, though!

Well, FYI the problem w/ the modem was fixed.  For everyone's knowledge,
this is what I did ...

What fix it was the use of the "isapnp" tool.  I'm not going to get on how
to install stuff. A regular distribution should have all the needed tools.
Okay, this are the steps:

1- My recommendation is to take a look at the output of the command
"procinfo" to identify the available interrupts and i/o ports before
physically installing the modem card.

2- If, by any chance, you have a file called "/etc/isapnp.conf," erase it.

3- Shutdown, install card, and reboot.

4- Now you want "isapnp" to take a look at what pnp stuff you have installed
by running "pnpdump > /etc/isapnp.conf."   (don't put the period)

5- Take a look at "/etc/isapnp.conf," and uncomment a setup that you know is
not already in use.

6- Now implement the setup by running "isapnp /etc/isapnp.conf."

7- At this point, the computer identified the card as it is, but there are
still somethings missing ...

8- Go to "/etc/rc.d/rc.local" or other file at the same level, and at the
end of it type:

"setserial /dev/cua3 irq 3 port 0x2e8 uart 16550A baud_base 115200."

Of course, you can change it in accordance to your setup.  In my case, I'm
using device "cua3" with the stated interrupt, port, etc., which might not
be the ones you decided to choose.

9- At this point, you can reboot, and everything should be fine.  Note that
the reboot is not completely necessary, but recommended unless you want to
type more.  As you boot up, you'll see a two/three line statement about
"isapnp" and the same output you saw from running "isapnp /etc/isapnp.conf."

10-  At this point, you can run minicom to check if you're able to access
it.

I think that I didn't miss anything w/ regards to setting the modem. The
next step is to set up the ppp connection, if that's what you want.  Unless
you are *ic like me, you can set up the ppp connection really fast
using a program like "ezppp" or ""kppp," for example.

Good luck!
