I am using 7805 with the 89c51 to transfer data serially to PC the problem is that while the power is ON no data is displayed on the PC as soon as the I switch of the power a burst of DATA is displayed OR if the switch is made to ON and OFF several times then it becomes OK and start sending data continiously. I think that it is the problem with 7805 as I had connected Two 7805 with the single supply one for 89c51 and other for some other circuits
can any one know how to solve the problem.
