hello everyone....my program transmits 'SAMPLE CODE' continuously on the uart...chip 'm using is p89v51rd2..the problem is nothing is being displayed on the hyperterminal...i checked the TXD pin on the scope,i can c pulses there...i've checked the serial cable,shorted pins 2 n 3,even that works fine....watelse could be the problem..??help me out...
i keep getting aa hex.
nd there is a max 232 in the circuit... why will you not disclose (nd) if there is a MAX232?
what do you see when transmitting 'U' constantly?

hhey 'm sorry...i meant i can 'see' pulses there... nd there is a max 232 in the circuit...

anyhow, try instead to continously transmit 'U' that will give you a square wave with a frequency if 1/2 baudrate.
BTW you DO have a MAX232(equivalent) in the circuit?

checked the com port,baud rate settings as well...
