Responding to: ???'s previous message
"Is there any special note on using UART of AT89C52 with baudrate generator mode of its Timer2? "
--->Datasheet

"Upon transmitting string, the first character transmitted seems to be unpredictable. I use polled transmitting and receiving."

How do you observ? With PC? If so, first connect your mcu to pc via serial cable, then power both devices and then initialise the comm port. Your mcu should start sending data after you initialise the pc comm port.
