External 3Com U.S. Robotics 56K Message Modem fails - help

[Maaz]

Dear Gurus

I have an External "3Com U.S. Robotics 56K Message Modem", that works fine with redhat 7.2 and 9, but this same modem fails to work with RHEL AS 4.

As on rhl 9, I configured the modem and/or dial-up connection via "Internet Configuration Wizard"(after startx i.e. in GUI), and the procedure is just same as in rhl 9. Then in "Int Config Wiz" i select the "ppp0" and click on "Activate" button, and following error received

Cannot activate network device myisp!
Failed to activate myisp with error2

and if i dial from command line, its also fails.

#ifup ppp0

what should I do ?

Any1 can plz let me know any cheap external modem that works with AS 4.

Regards
Maaz

Shalom Maaz,

3Com purchased US Robotics. Most of their modems are supported by AS/ES 4 from RedHat.

Those are PCI, but they surely do work.

Might want to try FC 2 3 or 4 with your current modem.

Zoom is great. They have external modems that work with Linux.

Are you installing the modem on the same machine where redhat 7.2/9 were installed ?

Try to see if the com port in bios is open.

Best regards.

now its working ;), but with a prblm ;(

Here is the solution:

I ran wvdial the following output produced

# wvdial
.
.
--> Cannot open /dev/modem: No such file or directory

from this out I found a clue so I check /dev/modem file, but /dev/modem doesnt exist. I did the following to create the /dev/modem

# cd /dev
# ln -s /dev/ttyS0 /dev/modem
# ls -l /dev/modem
lrwxrwxrwx 1 root root 10 Jan 22 19:45 /dev/modem -> /dev/ttyS0

now Applications->System Tools->Network Device Control->Select the dialup->click on Activate.
I connected the Internet. ;)

But the two prblms
1, whenEver i reboot my machine, /dev/modem lost/deleted, so that I have to create it via
# ln -s /dev/ttyS0 /dev/modem, command after each reboot. Why ?

2, Once I created the syslink "/dev/modem" i can connect to the internet via Point-and-Click, but still #ifup ppp0 fails
# ifup ppp0
/sbin/ifup: configuration for ppp0 not found.
Usage: ifup

3, when i dial no modem sound( i m using dialup modem)

Plz also teach me how to configure the dialup connection from commands or using CLI
Plz Help

#ifconfig ppp0.... shows me public ip.
