Hello :) ,

It's working, but both clients (localhost and gprs) executes cmdClient, gprsClient is not used.

Correction - it is all correct!
I'll do some tests now

Gprs clients perfectly connects to the server and keep sending data.
Localhost client does not execute commands and just closes itself, even if there are some gprs clients connected.
If there is no connection, for I guess 500 sec, server closes itself.
And at last, on clients abnormal disconnection, threads remain connected.

Servers echo:

gprsClient [4227801339] running on 4
4227801339: Command response: data test

gprsClient [4227801339] running on 5
4227801339: Command response: data second client

gprsClient [4227801339] running on 6
4227801339: Command response: data third client

Command Client running on 7
cmdClient [859189299] disconnected

If you have some more suggestions, I would really appreciate!
