Check datastream in ser2net

[kottes]

In a linux modem I use the program ser2net. The connection to a extern host is made via port 2000. I need to check if there is a datastream through that port and want to trigger then a led to show that the connection is real working with the application on the extern host.
Has someone an idea how I can manage that. I am a real beginning python programmer

another package pyserial has the following monitoring capability: https://pythonhosted.org/pyserial/exampl...ial-bridge.

As I understand it, ser2net does as well, https://unix.stackexchange.com/questions...tual-ports
