#92773 - RS232
Responding to: ???'s previous message
Of course i had rs232 in between
and the Tx and Rx pins are not shorting .. they are fine..
Moreover even if i dont use a rs232 between '51 and PC it does not matter in this case as i only have the '51 rx pin connected to Rx pin of PC.. its like the cell phone sending the response to both '51 and PC parallely..
But my only problem is :
Instead of receiving OK, the '51 is receiving _y always .. at different baud rates / interrupt or polling !
