What's the simplest (free) way to share a serial port over an ethernet link? [closed]

Solution 1:

I think this might work for you:

Basically is a c# app (source & compiled)

Solution 2:

I've had good success with this Virtual Serial Port. It is free as long as you respect the license.

Do main POS (Point of Sale) products and a lot of stuff still runs on Serial Ports.

Have used this program for a Video Overlay from a POS system to a CCTV/DVR system, and also as a PMS(Property managment system) for POS to Hotel. (aka, room charges.)

You install the software on both the client and server.
