Re: TTL Ports
For information like this, the PIC18F8520 manual is your best friend.

http://www.microchip.com/download/li...x20/39609b.pdf

Start on page 199 of the pdf (197 in the actual manual).

The Tx and Rx pins of the TTL port are wired directly to the RX2 and TX2 (I'm pretty sure it's USART2) pins on the pic, so you can get all your info from the manual.
