Hi Mark!

No parity, 8 data bits.

I once wrote a program to receive asynchronous data at 9600 or 19200 baud for 
the TI-82. If you're interested, I can send it to you. However the big problem 
about that program was that each time you chose another calc or when the 
batteries got low you had to adjust the waitstates in the program, so for your 
project I recommend putting a cheap microcontroller (PIC, 8051) in between GPS 
and TI which listens to the serial data and converts it to TI's protocol.

Bye, Burkart
