Thinkpad feautures can change entries in the CMOS memory. CMOS is the 
"parameter store" if you like that the BIOS (which is the code that 
executes when the system is powered on) read. So people often refer to 
changing the BIOS settings, they actually change the CMOS settings that 
the BIOS reads. If you have enabled a new device or feature in thinkpad 
feature, it may have chosen to use the same IRQ, IO channel or memory 
address as the PC-Card modem is using, which could cause the iratic 
behavior that you describe.

I'm interested to hear that some TP 770E's had built in modems and 
others not. Was this a model with MWave still, that needed to have a 
small adapter inserted, like earlier systems ??

Perhaps yet another option, if this system doesn't need to be used on 
the road would be an external modem connected to the serial port ? If 
you could borrow one, this would be a way to prove the theory before 
considering buying a new laptop.
