You need to check the 600E's actual serial port hardware state.  There 
are three methods:

1. See if "tpctl -rsx" shows that the serial port is set correctly, is 
enabled, and is powered on.  If the tpctl command complains about 
/dev/thinkpad then it looks like your thinkpad modules aren't getting 
loaded. 

2. If lspnp doesn't give you "/proc/bus/pnp not available" then you can 
use lspnp -v and setpnp to see if your serial port is powered on and 
enabled.

3. Boot MSDOS one way or another (floppy, CD, HD, ethernet, etc.) and 
with PS2.EXE installed run "ps2 ? se" to see if the serial port is 
powered on, "ps2 se on" to turn it on.  Also check that "ps2 ? irq" show 
the irq assignment that you want, and that "ps2 ? ir" shows that the IR 
port is disabled or at least not assigned to the serial port you are using.

Once you know that your serial port hardware is powered on, enabled, and 
has sane IRQ and I/O address settings, then you can use setserial to 
tell Linux what those port settings are, and you should be set, assuming 
no broken hardware.
