Code for Send/Receive TTL/Comport Sample?

[wdmagic]

thanks thats good to know, ive been up all night messing with VB, ive got it set up to convert 2 - 8bit numbers to their ascii characters and then I can send that to the PIC, I should be able to just use those as 2 seperate bytes, i could use byte 1 to control the HPWM and byte 2 to control PORTB outputs. later I can add more bytes for other stuff but this should be enough to test with I would think.

how do I go about receiving data either on the PIC or the PC, On the PIC do i just make a loop with HSERIN? On the PC do I have to have a timer just sending the data over and over? or does the SEROUT just keep sending the data over and over on its own? I just wonder if when I get to the code to send data to the PC, what if the PC isnt listening right that instant?
