[En-Nut-Discussion] Dual rs232<->Ethernet

[Ulrich Prinz]

Hi!

I am not sure, if I understand that correctly:
You'd like to communicate with two RS232 ports via TCP/IP.
In nut/app/rs232d there is a demo for doing that with one single port. 
So you can duplicate the THREAD and assign the second one to a different 
port. As a connection like that cannot be shared, only one client can 
access one RS232 port. So you do not need to take care of launching 
several threads per port.

To access GPIOs of the CPU there are different options. You can watch 
the RS322 communication an catch special commands, that are not routet 
to the RS232 port but are used to control or read GPIOs.

Or you can launch a third server thread that controls the GPIOs.

If your code doesn't work, you can post parts of the code in here, so we 
can help.

Regards
Ulrich
