I need to communicate using serial connection to both PC and GSM module using PIC16F877A. How am I suppose to do with this? I really need help.. Only one serial is working the other is throwing random data.. I use Hserial for GSM and Rserial to PC, only the Hserial is working... I am programming the PIC using proton basic.. according to it's user manual, pic can communicate to any number of devices using software serial communication...:sad::sad::sad:
 

Hi,

If both serial com. have to work simultaneously, software serial com. can not be used. Hardware UARTs has that capability for some extent. If you need 2 hardware UARTS try 18F24k22 or 18F25k22.

Thank you,
