AVR-Chat

If you don't want to do the hardwiring yourself (no big deal really) you 
can get a DB-9 to DB-25 serial adaptor.

If you don't mind doing the hardwiring, do a Google search for "DB-9 
DB-25 RS-232" or something similar and you'll find a schematic of the 
wiring pattern. You most likely only need three wires.
