HI, I have designed a controller for a system for my project. I have interfaced RS 232with it and rx and transmit data to DS89c420. I have been asked to stop all the operation on entering a particular char say Q, my question is dat is it possible to run a side program that monitors the SBUF continuously on side of the main program... I did monitored the SBUF at the start nd end of the main loop but since the SBUF gets d data regularly from the main program, any thing i enter in between the program will get over written.. Plss help me .
I almost forgot this part..will see the RX part nd implement it..Thnx for the correction :)
