How it works
In most cases, Serial Port Redirector acts as a client for getting access to remote serial devices.
For this purpose the program creates virtual COM ports on the local side.
The virtual serial port is configured for connection to specified IP-address and TCP-port of the remote side.
As soon as communications software opens local virtual COM-port, connection with the remote side is established.
Hardware Serial Device Server usually serves as a remote side.
It accepts incoming network connection from the Serial Port Redirector and redirects both the data stream and control signals to a plugged serial device.
