Hi all,

I am using PIC18f452 to communicate with Wavecom 1306b modem. I used only RX,TX and GND pins. I can communicate with the modem using HyperTerminal with the use of only these three pins.
I am using MAX232 as logic level converter and checked the MAX232 Outputs also with PC. It was also OK.
But I can not communicate with the modem by PIC.
Please guide me to solve this problem.

Compiler: MikroC
Serial Communication: USART
oscillator:20Mhz
Baud rate:9600

Thank You very much
Amila
