Please be more specific. How are the computers connected? Using a TCP/IP network? Using RS232? Something else? What is the OS?

Search for source for zmodem or kermit. For example: http://pauillac.inria.fr/~doligez/zmodem/ and http://www.columbia.edu/kermit/ .
These are protocols for data transfer over modem lines.

For sending data:
  1: using CreateFile("COM1"or "COM2" , .....) to get a handle .
  2: call GetCommState() and SetCommState() to set parameters.
  3: write encodeFunction(text_str, ...) to encode text_str.
  4: call WriteFile( handle, text_str, ......) to send encoded data to the connected serial port.

For receiving data:
   finish the similar steps.
