Appendix A. Using Virtual COM
The
Virtual COM
software/driver emulates a serial port with Internet or LAN topology. In the Virtual
COM Mode, COM port data (RS232) is encapsulated to Ethernet data format. By creating a virtual
COM port on a PC, the Virtual COM driver redirects communications from the virtual COM port to the
destination IP address (and the designated port number) by encapsulated COM data into IP data.
