Thanks for the reply.  So it sounds like what I would want to do is
create a startup loop that checks the RS232 for characters, and when
it receives them, have it stuff the needed ones into EEPROM.  Do I
need to worry about things like checksums for the data?  I really am a
newbie when it comes to RS232.  I don't want the EEPROM getting
garbage and blowing things up.

Secondly, after everything gets updated, can I reconfigure the PD0 and
PD1 (rxd and txd) back into outputs?  I'm not sure if they can be
changed on-the-fly in the middle of a program.

I'm currently working with bascom for my sanity...  Grew up with
basic, so it's almost like a comfort food.  :)
