    Default Modem configuration in linux

    I have just finished configuring my linux system to work like I want it to. The only problem is the modem. Whenever I restart the computer, I have to use the setserial command to make the modem respond. HELP!

    Default Re: Modem configuration in linux

    There are two ways to do this, the right way (with a script /etc/rc.d/setserial -- as described in Modem-HOWTO) or another 'good enough' way which will work -- adding the setserial command as the last line of the rc.local file. There's a description of this at: . The third way ... (this is a Unix and there are always LOTS of ways to do anything) is to put the line in /etc/profile ... but its better to have it in the booting sequence rather than do it at login time.

    Been a long struggle, hasn't it. Now enjoy it.

    Just another thought...

    If the serial ports aren't being picked up correctly the BIOS may need altering.
    If your BIOS is set up to expect a Plug & Play OS then Linux may not pick the ports up.

    Type the following command to inspect your ports.

    setserial -g /dev/ttyS*

    if it comes up with something like:

    /dev/ttyS0, UART: unknown, Port:OxO3f8, IRQ: 4 & the UART is showing up as unknown, then linux hasn't detected them.

    Go into your BIOS, find the option for P&P/OS and turn it off, save the settings & reboot.

    This time the kernel should detect them correctly.

    Might not be the answer but it's worth a go.
