Just look at reading/writing data to/from the serial port. Note that this is HIGHLY OS dependant, so whatever operating system you use will determine how this works. Under win32, just look into the WinAPI to manage serial ports. Note that you might not be able to use DOS commands on serial ports because this might be forbidden by Windows (I am not sure what its rules on port access are).
These might help a little bit:
