Check this serial port emulator http://com0com.sourceforge.net/. I used it a lot for simulating serial ports. You will probably need a sniffer. Modbus protocol is pretty straight forward to implement these days, specially if you only need to handle two end points communications. The above link given by Phantom is the canonical article for the serial port communication software design at windows.
