Form where can i find tutorials about port programing in C?
Here are a couple of sites I located using google that may help.





www.codeproject.com/system/serial.asp


www.beyondlogic.org/





Personally, I found a company that wrote some library functions distributed in a dll and used that for programming my serial port app.


I don't have the information on this computer though and the library wasn't free. It was something like $200-500 but as a one time cost. No cost to distribute the .dll when distributing your app.


Good Luck!
