I want to do some Lame Multiprocessing.....

Asif Ali Rajput

I am doing a project and in that project i am using one MAX232 but with multiple Microcontrollers i know that i cannot use RS-232 to multiple Microcontrollers but i am using MAX232 to convert the RS-232's 23V to TTL (5V) and so as the RS232 is converted to TTL so i think that it will work for multiple Microcontrollers (am i right?) well this is my stratigy ...

but my main task is that i want to send a HexaDecimal no through the Serial port so that the approriate Microcontroller will responce .... so i have coded some code but as i cant see the value came into SBUF in keil so could any one help me ?

    Actually, that's an implementation detail rather than your "main task"!

    Have you looked at the 9-bit Multiprocessor mode of the 8051 UART?

    int i=1; //global variable which is to be compared

    Are you sure that you want the numeric value 1 (0x01), or do you really mean the character '1' - ASCII code 0x31?
