OK, I set up a simple loop to send Z-A with a 200 ms delay in between characters and 1/2 second delay in between repeating the Z-A sequence. Basically I decrement a register from H'5B' to H'40' not sending the 5B or 40 just 5A to 41. Olin, sent me a link to a macro for the baud rate calc but WWW.embedinc.com has been down since yesterday. Can anybody forward me this macro ? I have a F84, 4mhz xtal trying to send 9600,8,n,1. the code is from http://204.210.50.240/techref/microchip/rs232at9600on16F84noint.htm I calculate a Baud rate delay of 33.
