if you use standard PC cable you have probably this cable schematic:
PIC16F877 - Siemens C55 - max232 - rs232 SMS Sending : 8051 Microcontroller Projects AVR PIC Projects Tutorials Ebooks Libraries codes
So you must have power supply over RTS lines for example......

Why not direct connecting com lines?
