thank for help

I think you have to make sure that there is communication with the module.

Did you check that the module is responding?

Ioannis

I can not check Module

I can use X = 4 MHz for buad rate 115200 bps ??

RX & TX is TTL level I can connect Module to PIC16F877A or module to max232 ??

thanks for help

sorry i bad eng

I am on a mobile phone and cannot check data sheet for you PIC but I thing you cannot use 115k with 4Mhz xtal.

As for the TTL level use it directly to Pic without max232.
