RS-232 to TCP

Rabbit
1

I have 3700 cores and wanted to create a simple program to take serial in, and then push it out via Ethernet. I have a skeleton program, but do not know how to initialize sockets and the best way to send the data out on the tcp socket.

Any help would be appreciated.

Thanks,
Alex

I`m trying to do the same thing using a RCM5700, have you succeed in the question that you make because I’m having the same problem that you mentioned…
