Thanks for your time dhouston.

I've tryed the Serin2/Serout2 version but i couldn't receive any message

Since my modules work at 19200 i changed the code like ( the rest is the same as you posted ):

TX
Code:
SerOut2 tx,16416,["HELLO",10]
RX
Code:
SerIn2 rx,16416,[STR msg\5\10]
lcdout cl,row4, "received - ",STR msg\5
