Well. After several requests, I've added the Timer 2 reload calculation to the Baud Rate calculator at http://www.keil.com/c51/baudrate.asp. Nothing is changed for Timer 1. For Timer 2, displaying 64K reload values takes too long, so I limit the results to reload values that match standard baudrates. I added a baudrate target input box so you can enter a specific, non-standard baudrate. Hopefully, someone would be kind enough to check my work and make sure that the results make sense. Thanks, Jon
