Laptops :: Thinkpad 380XD Serial Port

I would like to get this old IBM to talk to routers and muxes and such via the serial port. So far I haven't been able to get it working.

I even installed Win98 just to test the serial port. It worked fine on COM2 @ 9600. Talked to a Cisco router and everything.

I cannot get the serial port to work in DSL. I have tried Seyon, Microcom, Minicom and CuteCom. I am new to Linux and don't know what diagnostics/drivers are available or how to use/install them.

Any help would be GREATLY appreciated as this old laptop has seen it's last days if it has no operational serial port!

Thanks!

Nobody can help me out with this serial port prob? I know the machine is a shit-box but it's the LAST tweak I have to make it PERFECT....HELP!!!

Have you tried all the possible serial ports?

/dev/ttyS0 = com1
/dev/ttyS1 = com2
/dev/ttyS2 = com3
/dev/ttyS3 = com4

try, as root, setting the perms on the /dev/ttyS1 ( com 2 )

chmod 777 /dev/ttyS1

I am not sure what perms are on the serial port but i did what you suggested. Still no serial comms.

Microcom tries all the ports on startup but finds nothing. When I force it to use any of the ports (w/ -D/dev/ttyS0 1, 2, 3 or 4) it doesn't work at all. I have also tried the ~ for port configuration with no luck.

I also installed minicom via synaptic. I have tried using the proper port config to access a Cisco router on ALL ports but still get nothing.

As i posted before, the serial port is operational in Windows 98SE.

Any other suggestions?

As an added note to my above post...

I did a cat /proc/interrupts and did not see SERIAL on the IRQ list.

I don't know if this helps or what...but I thought I should throw it out there.
