The laptop in question has a built-in dialup modem which doesn't even show up as a serial port in Linux. In the P.C.'s setup screen, it doesn't show up there so I can't remove or move it out of the way, but a PCMCIA card installed containing a real truly RS-232 port tries to come in as ttyS0. That internal modem is probably the reason why /dev/ttyS0 acts as it does. One can not send from it, but one can receive.
Is there a way to fake out the system to make it assign /dev/ttyS1 to the PCMCIA port? That would probably make it work. Thanks for any ideas.
