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 ?
""i cant see the value came into SBUF in keil"
What have you tried?
Have you run this in the simulator?"
Yes sir i know that i cant see it in simulator.... because you have told that in another thread.
You CAN see received bytes. you can not see transmitted bytes.

Actually, the Simulator has separate VTREGs for the transmit and receive halves of SBUF - so you can see them both in the simulator!
Look-up "VTREG" in the uVision Manual...
