B4J - jSerial

jSerial library

The jSerial library allows you to open and communicate with other devices through the computer COM ports. It can also be used to communicate with Bluetooth devices over a virtual com port. (jBluetooth library is now available: https://www.b4x.com/android/forum/threads/jbluetooth-library.60184/)...

Wow wow wow and wow
I often use communications via rs232 and hercules for both rs232 and tcp client/server
And even if I still don't quite understand what the program you indicated does ?, I think it will be the next toy to test
Compliments

Thank you so much @amorosik

The WebApp is for communicating with a com port via the jSerial b4j library.

On my side however I don't have any com ports on my laptop, so I had to emulate them. So I created a bridge between com12 and 13 on the emulator. With Hercules, I can open a port and then send stuff to it. So this is more like a chat application.

The webapp is developed using BANanoServer, the jetty webserver built for BANano.

One thing is not clear to me, being a webapp, it means that a browser physically running on pc1 connects to a webserver physically running on pc2
It could also be on pc1 but it is to understand better
But the serial port (in this case one of the two virtual ports com0com) with which the Jserial library of the webapp communicates is on pc1 or on pc2?
