Hardware Modem

Can anyone suggest a good internal Hardware Modem that will work with Mandrake 9.0?
Thanks.

Any hardware modem should work if you install setserial that is not installed by default.

# Configuring a real hardware pci modem
To configure a pci modem, open an x terminal and su - to the root account:

Code:

[fancy@tinwhistle fancy]$ su -
Password: 
[root@tinwhistle root]# cat /proc/pci

Look for your modem in the returned list. Look for something similar to mine:

Code:

  Bus  2, device   2, function  0:
    Communication controller: PCI device 151f:0000 (TOPIC SEMICONDUCTOR Corp) (rev 0).
      IRQ 5.
      I/O at 0xc400 [0xc407].

With this info, I use the setserial command:

Code:

[root@tinwhistle root]# setserial /dev/ttyS0 irq 5 port 0xc400 uart 16550a

Then I test the modem with the internet connection wizard and it works. I edit /etc/rc.d/rc.local and enter the setserial command:

Code:

[root@tinwhistle root]# pico -w /etc/rc.d/rc.local

My file for an example

Code:

#!/bin/sh
# Redhat /etc/rc.d/rc.local file
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
# configure modem
setserial /dev/ttyS0 irq 5 port 0xc400 uart 16550a

Now, it remains configured after a reboot.

I have a U.S. Robotics PCI Modem (USR5695), but I haven’t been able to get it working with what I’ve done so far. Could you please look at what I’ve done and let me know if it looks like I’ve messed anything up yet?
Is it still possible to get this thing working?
Problem im getting is, after I add my setserial information into the rc.local file, I type ./dev/rc.d/rc.local and keep getting the message /dev/modem: No such file or directory.
When I initially tried to install my modem this is exactly what I did.
1. rm –f /dev/modem
2. ln –s /dev/ttyS1 /dev/modem
3. vi /etc/rc.d/rc.local, and edited my rc.local file adding the following line:
setserial /dev/modem uart 16550A port 0xblah irq 11
4. I type ./etc/rc.d/rc.local, and I get the message /dev/modem: No such file or directory.
Also I’ve tried switching the dev to ttyS0,ttS2 and ttyS3, as well as changing the rc.local setserial line from:
setserial /dev/modem uart 16550A port 0xblah irq 11
to
setserial /dev/ttyS1 uart 16550A port 0xblah irq 11
The output error is slightly different now saying:
/dev/ttyS1: No such file or directory.
Should I rearrange the port and the irq in my setserial line above to match yours, do you think?

On a last note. I do have a driver I downloaded for my modem (I hope).
I have installed it but I have no idea where it went. Is there a certain place I should install my modem driver? Or should I just go to my driver .rpm file and just open it right where it's at (which is currently in my downloads file).
Sorry for typing a book here, but I want to make sure you have all the information.
In case you may be able to help.
Thank you =0)

Hmm... you did the ln –s /dev/ttyS1 /dev/modem and got no errors?

Post the modem part of the output of /cat/proc/pci

Maybe I spotted the trouble:

Quote:

setserial /dev/modem uart 16550A port 0xblah irq 11

You should have gotten an error, I think. try setserial /dev/ttyS0 or any other unused ttyS<N>, then make the symbolic link for /dev/modem that points to the real device

You could use the actual /dev/ttyS<N> that you used rather than /dev/modem in the connection config.

Thank you for taking the time to help =0)
Heres the information from cat /proc/pci
Bus 0, device 9, function 0:
Communication controller: US Robotics/3Com USR 56K Internal WinModem (rev 0).
IRQ 10.
Prefetchable 32 bit memory at 0xe0004800 [0xe000483f].
Prefetchable 32 bit memory at 0xe0010000 [0xe001ffff].
Prefetchable 32 bit memory at 0xe0008000 [0xe000ffff].
I/O at 0x1040 [0x107f].

I’m trying the switch you suggested right now…
Sorry if it takes a few minutes to respond.
I’m running back and forth between two computers.

That's a winmodem

But, there is a driver available (I think)

Oh my

This is way above and beyond the call of duty.
I’ve never had anyone actually help me look for information before.
I hope you know I really appreciate your time and effort.
I’m reading all your recommended sites so your efforts are not going to waste.

I’ll let you know if something happens.
Unless the computer explodes…
