vCom 4.3

The vCom driver emulates two ports talking to each other through a null modem cable so installation of ports is done in pairs. You can select up to 10 pairs (20 ports) and give them any port names (COM5, COM6, etc) as long as you do not duplicate an existing port name on your computer. Vcom is used to create virtual com ports in software(null modem cables) to allow CAT, software keyer and PTT control to other programs from PowerSDR 1.x or any other utility that used serial ports.
