I wish to write an MFC program that sends/receives data from COM2. &nbsp;I know i can't use the inp and outp calls found in dos programs. &nbsp;Are there any API functions that I can use? Can I use CFile to open and read/write to a serial port?<br />
I would appreciate code snippets. &nbsp;Many thanks!!!<br />
