I have a gadget made by Moxa called an Nport server, which makes 4 COM ports available on any machine on the local network. The thing has an IP address in the private IP area .
The question:. If I have a serial device connected to this thing, how much else is needed to access that thing from a PC elsewhere on the net. Say there is an app that normally talks direct to the serial device via COM1 - instead I want to run the app elsewhere and still make it look at though the serial device is connected to it.
Do I need more hardware or am I just a few mouseclicks away? I obviously can't go half-way around the world and expect to be able to find the thing at 192.168.0.xx on another PC.
I can do this on the local network - the NPort thingy comes with software that finds the private IP address and connects to the ports on another PC on it. You can then map those ports to (say) COM10..COM13.
