Appendix A: Using Virtual COM
Virtual COM driver mode for windows converts COM data to IP data to control the RS-232C port on a SW
via the IP. 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 SW that connects the serial line device to the
network. The following figure is Virtual COM connection diagram.
