Yes, there is software that bridges a serial connection over a
network.  On Windows it is often called a "virtual com port" or
"virtual serial port" or "com port redirector".

Open Source Linux:
ser2net

(ser2net is available in many distro package managers)

Open Source Windows
hub0hub and com0com
https://sourceforge.net/projects/com0com/

Freeware (Windows):
