Are there any utilities that would help me identify a possible serial
port problem? I have a NEC Versa 2000C laptop computer. It has a
built-in modem at /dev/cua1 (0x02f8, IRQ=3, uart=16550A). The modem
shows up fine. I ran minicom to it and it's responding to AT commands.
According to the NEC website, /dev/cua0 should be the serial port (0x03f8h,
irq=4, 16550). Since the uart for the modem is an "A", I suspect the website
may have to data wrong and it too should be an "A" for the serial port.
Using the setserial command, I tried to auto config this port (using this
method leaves the uart as "unknown"), and I tried to set it manually. In
both cases, I get errors when I try to attach AX.25 to this port.
I'm also wondering if there has to be something set via the BIOS. If so,
could someone tell me how to interrupt the boot up? Hitting the ESC or
DEL key doesn't get it. Any ideas would be greatly apprecieated.
I'm running SuSE 5.2 on this machine. Other than this serial port
problem, everything including xwindows is working fine.
Thanks,
Dave
