serial port not showing on thinkpad: dmesg.txt

[Janina Sajka]

Cheryl:

Are you saying you get no speech over the serial port?

I've heard that the physical db9 port on the backplane of newer Thinkpads 
is now actually being assigned to the first serial device by default. But, 
perhaps this unit is setup along the lines of all older IBM Thinkpads, 
which default to the first serial device on the infra-red port. Because of 
their bios limitations, I believe you can only have one or the other, 
infra-red, or rs232c on the db9 port.

Of course this can be changed in cmos.

It can also be changed from DOS. Create a boot disk that boots DOSm, 
preferably with speech. You should have a directory called c:\thinkpad. If 
so, the following should fix you right up. Turn the following into a batch 
file and execute it. You will need to reboot for the changes to take 
effect, but this should get that db9 port working.


@echo off
c:
cd c:\thinkpad\
ps2 serial on
ps2 sera enable
