I've googled all day and night and I'm at the point now where i just want
someone to tell me the answer!
Could you just run through what happens, say I had a programmed PIC, and a
MAX232, 4 ptm switches and a serial cable. Here's what I understand..
I press a switch, which sends one of the pins on the PIC high, the program
on the PIC says "ok you pressed switch 1, i'm gonna send 'A' to the MAX232".
Does this go along and into a pin of the max232, and then the max232 does
Also, I have heard of these UARTs - are they simpler/do I need extra
equipment to use them (like something to program them with)
Thanks so much,
