i am making project to switch devices with GSM
can anyone give me detail hoe to interface 8051 and modem i have kit easy8051 microelectronika with rs-232.
how the asm code to be written to intreface gsm modem with AT commands.
Did you expect many people to busy themselves answering the same questions?
How many more forums have you posted to?

By the way - there are no "one" way to connect a GSM to a microcontroller. It depends on controller and GSM module/phone and supply voltages and available interfaces etc.
You either know assembler, or you don't. If you don't, then consider using C instead. Why? Becaues the code will look very similar for different processors, so there will be a huge amount of examples to be found using Google.
i want to just know that what is the output of GSM modem?
.
A modem is a communication device; it doesn't have a single "output" - both the DTE interface and the air interface are two-way!
Since you've posted the question to multiple forums, it is up to you to monitor all those forums, and respond promptly to all contributions that you receive.
Please check all your other threads, and respond them!
sorry!! for your valuable time i wasted...!!
i m new to these type of forums and dont know how to use it effectivly..so made mistake.. and also i think i choose wrong forum..
i serach for GSM on this forum.. and all answered like me...! i dont want source code or schematic..just want to know basics..
i think if one think that the question is repeated or wastage of time ..then just leave it unanswered..

which all will be in the datasheet for the modem.
