What is a Virtual COM port?

A Virtual Port (aka COM port redirector) is a specialized software (often including

device driver and user application) that includes the underlying network software

necessary to access networked device providing remote serial connectivity.

In figure below, you have a real Serial link between a computer and a Serial device.

With this direct link, the main limitation is the length of the cable (few meters).

To get rid of this limitation, you can use an eWON beside the Serial device and install

the eVCOM software on your computer to create a virtual Serial Port linked to the

eWON.
