on the laptop, im trying to connect and setup a _serial network_ using 
windows 95's direct cable connection (which establishes a serial 
connection between two computers and treats the serial cable as a 
ethernet cable).

to use DCC (Direct cable connection), you have to have a cross over 
cable (aka laplink cable or null modem cable (where pins 2 and 3 are 
swapped)).

one thing i didnt try when i tried getty was setting the parity (stupid 
me), im gonna try getty again WITH the parity.
