4. Using Virtual COM
Virtual COM driver mode for windows converts COM data to LAN data to control the COM port on a SE5404D via
the LAN. By creating virtual COM ports on the PC, the Virtual COM driver redirects the communications from the
virtual COM ports to an IP address and port number on a SE5404D that connects the serial line device to the
network. The following figure is Virtual COM connection diagram. (ref Figure 4.1)
