From the developer:
HsTcp2Com is a communication application for Windows which allows to forward / bridge data between serial ports (RS232, bluetooth, IrDA, USB) represented as COM ports and TCP/IP connections or UDP/IP links. In the simplest scenario it is an COM port to TCP/IP converter, but it can bridge data between any combination of COM and UDP or TCP ports, with TCP ports in either client or server modes.
