Chapter 5: Using Virtual COM
5. Using Virtual COM
Virtual COM driver mode for windows converts COM data to LAN data to control the RS-232 port on an LES301A 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 an LES301A that connects the serial line device to the network. Figure 5-1 shows the Virtual COM
connection diagram.
