Simple Serial communications

[BobK]

Hi Kitcat:

Since you are writing your own VB code for the PC why not have the PIC pause 100 after receiving the 2 bytes then send them right back to the PC and have the VB program acknowledge the data was sent correctly? All that dts & rts lines are for is handshaking back and forth.

Yes. Hmmmn. It really is that simple isn't it. I think that was lurking in my head but it seemed too easy.
Thanks for that.

Check this Thread as an example for PC to PIC and echoing back to PC.
