Pair device

Pair is a simple device that consists of two logically connected virtual ports.

It is usually more popular solution than Connector device. If baud rate emulation is checked, VSPE will try to slow down data stream to conform with the current baud rate, but it may be quite inaccurate.

This device does not create virtual serial port. It uses existing one 
that can be either physical or virtual (for example, Connector).
