VB interfacing serial port of a PIC16F628

hi, i am working on a VB interface with the serial port of a PIC16F628 and i need to send a any character to that serial port

how could i do that ??

You have to use MSCOMM ActiveX control since there is no in-built function in VB to send data to any hardware.

If you are planing to receive as well, make sure to change RTreshold to non-zero value (1 works fine for testing).

You can also use an ActiveX control if you are using a form in Access or Excel. I have recently used this method to transmit the progressive Bingo Jackpot Value from the database to a video overlay unit that displays it on all TV & big screens around the bingo hall. Real easy to use too. Do a search on "JS Payne". You can download a trial version; no registration or anything.
