How do printf with hyper terminal (COM2) my code is bad !!!
Beware. Early versions of hyperterminal were not allways fully "functional". Next, be sure that you have set a valid baudrate for the 8051. You can check the possible baudrates at http://www.keil.com/c51/baudrate.asp Jon
Early versions of hyperterminal were not allways fully "functional". that's the polite way of putting it ;-) IMO, hypoterminal is more trouble than it's worth.
That's why some brite individual here copied the terminal program from Windows 3.1 and used that!!! Jon
A very sensible chap, I'd say!
