Would someone be able to tell me how to initialize the serial port on the C515C so that when I send a printf statement I'll be able to read it on HyperTerminal. It could be that I have not set up the baud rate, stop bit, and flow control on the HyperTerminal so any comments on this would be appreciated
Make sure that the oscillator frequency you have allows the baud rate you want. For example, 9600 baud is not possible with a 12MHz using timer 1. See http://www.keil.com/c51/baudrate.asp for baudrate reload values for Timer 1. Jon
