Hi, I am having problems interfacing my sim300 Modem (NOT module) to my 16F877A. I am using max232 level converter. When I connect my modem to PC serial port, it works fine.
Also when I connect my PIC to my PC via Max232, it works fine as well.
But I dont get any reply from my modem when I connect RX, TX & Gnd with my PIC. (Tx , Rx via Max 232)
Can someone help me understand what I am doing wrong? Is it any connection I am missing or something?
Thanks
