Appendix A. Using Virtual COM
Virtual COM
driver mode for windows converts COM port data (RS232) to IP data to control the RS-232C
port on a STW-602C over the IP network. By creating Virtual COM ports on the PC, Virtual COM redirects
the communications from the Virtual COM ports to an IP address and port number on a STW-602C which
connected to the serial devices. The following figure is Virtual COM connection diagram.
