I'm having a problem here, I have a modem that worked on a linux machine perfectly. Suddenly, it doesn't work any more. Linux no longer can see a modem on /dev/ttyS0
Linux doesn't see it using the wvdialconf command.
The dialup modem is hooked up through the serial port (/dev/ttyS0). I use wvdialconf to have it work correctly.
What could be the problem, is there a special lock file I need to manually remove? How can I debug this problem?
By the way, its not a modem problem because the modem works when connected to a different linux machine.
Here is the output of the wvdial.conf command:
[root@localhost ~]# wvdialconf wvdial.conf Scanning your serial ports for a modem.
