    Yeah, it's TTL alright, but I just used a max 233 level shifter. I also 
think its the wrong polairity... Note that the MAX233 inverts as well as 
level shifts.. I dont remember if I inverted the siginal prior to feeding it 
into the MAX233, but it may be necessery. Its also helpfull to note that the 
PC's UART can be SOFTWARE configured to almost any baud rate. It has a 
16-bit divisor that sets the rate. This means you dont need any special 
hardware (besides the level shifter) to hack at this project.
