Connect serial interface to existing TCP server with host and port

Open frank-deng opened this issue 4 years ago • 5 comments

Is it possible to connect serial interface to a existing TCP server apart from TTY devices, using SDL Net? I've tried socat before but never succeed.

Thanks to your nice idea. It's interesting.😁

NP2kai's serial I/O connect to devicefile provided by socat? (Or NP2kai's serial I/O connect to SDL_net?) I'll make time for research!🔍

Maybe it's better to use SDL_net, socat seems to have more limitations.

I've tried SDL_net with some testing code in my forked reporsitory, but NP2's serial seems to works differently from SDL_net and I can't read anything from the TCP server yet. Also I cannot read the newly added configuration items from config file even if I have added all the things needed, and I had to hardcode the configurations for testing.

I haven't figure out the meaning of the return codes for serialread, serialwrite, serialgetstat.

This issue, It must pseudo HW(SDL_NET) NIC on 98x1 system. Then It needs a bit technical.
