Hello sir, thank you for the code.
i am designing a project for gsm based automation, i send a message and the relay unit responds to it by on and off, i'm having hard time programming my logic, can you help me with it.

Thanks.

If you want I will write a code for you. Can you use mikroC PRO 8051 Compiler. Mention which MCU and what external crystal frequency you are using.
