Hi! I'm sorry to bother the lists with this (probably over-asked) question, but I'm only getting back into PIC-related development after a long time away. What are some of the best ways to do RS-232 style asynchronous serial communications with a PIC16C84? I'd like to use just two lines (transmit and receive) with software hanshaking (XON/XOFF) if necessary to save me a couple of I/O lines that I need for other purposes. Yes, it has to be RS-232 style so we can hook it to a terminal (or to a GPIB<-->RS-232 converter). HALF duplex is just fine. Speed is NOT critical. I'm looking for software suggestions mainly, though if you'd care to comment on which I/O pins might be best to use for any particular chunk of code, I'd be glad to get your input. Rick Miller
