How to access COM over your network?

In order to access COM ports over a network, you need to set up the serial port for remote access on the remote computer.

When you connect a serial device to the serial port of the Serial Computer (the server is the local computer where the serial device will be attached), the device will appear in the list of devices on the client machine.

A virtual port that is created will behave exactly like an actual physical port. Any device connected to the server machine will be accessible by the client as if the device was physically attached to the client.
