I am attempting to upgrade from Fedora 2 to Fedora 4. After doing the update, I
can no longer use the serial port and external modem. When I originally
installed Fedora 2 I had the same problem. Then I took the computer back to
where I bought it from. The support people got the serial port (and modem) to
work and told me the problem was that Fedora did not work with the chip set
used in the computer (VIA K8M800 + VT8237R).

They also suggested I upgrade to Fedora 4 which should support the serial port
with that chipset.

I did the upgrade but now the serial port no longer works. Rather than pay
another $100 to have the problem patched again, I would like to do the patch my
self. I tried doing a web serch using google but did not find any information
about a compatibility problem with Fedora and that chipset.

Does anyone know about this problem and how to fix it?

Thanks

If no ideas show up consider the cheapest internal modem you can find even used
if the speed is right as older is better.

Quite a lot of internal modems are software modems and are usually made for
Windows , not linux.
What you really should have suggested is to get a internal HARDWARE modem
that can be run on both Windows and linux.

The support people are full of it. The VT8237R (via the VT1211 LPC) provides
standard 16C550 UARTs, which have been supported by the linux kernel, well,
since forever.

Check your bios settings for the serial ports, make sure it has COMA at
0x3F8 and COMB at 0x2f8.

Check your /var/log/messages file after reboot for similar to the following lines:

/var/log/messages:Aug 22 08:30:38 systema kernel: Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled
/var/log/messages:Aug 22 08:30:38 systema kernel: serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
/var/log/messages:Aug 22 08:30:38 systema kernel: serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

The bios settings matched and the messages described above were in the
/var/log/messages file. However, when I tried to activate the connection I got
a "Failed to activate with error 2" message and the messages file showed the
following message:

ifup=ppd: ppd started for Eskimo on /dev/modem at 57600
pppd[2713] unrecognized option '/dev/moPdem'





What does this mean?

It means you have a typo somewhere in a config file.

Try using /dev/ttyS0 instead of /dev/modem.

Thanks, switching from /dev/modev to //dev/stty0 worked
