I am using a PIC16C74A and the built-in UART feature. I am trying to interface to a PC Serial Port (standard RS232). However, I don't know if the PIC outputs are at RS232 or TTL levels. I suspect the latter, but I haven't seen anything in the data sheets definitively either way. Do I need a RS232 level-converting chip? What kinds are out there and what kind do you recommend? Thanks for your help, Jason Williamson -
