Serial Port Over Remote Desktop

Question

need your help.

I have this scenario:

I have to comunicate to a Printer connected to Serial Port, over remote Desktop, in bidirectional communication, it means, i want to send comands to the Serial Port, and get the response of the remote printer, all of this in Remote Desktop.

I successfull can connect locally, i can send commands to the printer in the remote Desktop with a Spooler, but locally i can get the response that the Printer sends me when all finish (close Fiscal Document).

I have tried with c#, but this only works when i the Printer is connected in my local machine.

I am sharing ports, printers in my remote desktop communication, but i cannot get any response from the remote Printer.

How can i do that?

Any help, will be appreciated. Normally I will send some code, but, i just want some help of you telling me if that is possible, or maybe if you have some examples or guides.

Regards

Firewall is blocking communications.
