Dear:
I am trying to interface NokiaGSM 6100 cell with PIC16F877A @ 9600bps.
Problem: Nokia6100 responds OK on AT in Hyperterminal but is not giving any response in Serial Communicator. Serial Communicator COM, Baudrate,Parity, Bytesize & Stop bits settings are same of that to Hyperterminal Program.
Is there any other settings i need to do? Need ur expert advise?
Thanks in advance.
Did you use a level translator (as Max232) for connecting TTL (pic) to RS232 (modem)?
Al.
I have directly connected Nokia 6100 to PC right now.
It is working perfectly when i try to communicate Nokia 6100 with Windows Hyperterminal but on same settings, It is giving no response in Microcode Serial Communicator.
What can be the issue? Are there any special settings for handshaking protocols?
Waiting for your response.
