My silly blunder here was: I was interpreting the instruction in the users manual as being 16 (0x16) instead of decimal 16. Once I figured that out, I was able to look this instruction up and understand it properly. Sorry to waste list bandwidth.

Beq+ 14 <outbyte+0x14> This is what is in the disassembled object file. I can't find this instruction in the programming environment manual so can't figure out how it is suppose to work. It is branching to itself and hanging my code. It is suppose to be polling a bit in the SCI interface to check and see if the transmitter is free to transmit another byte, but it never moves on from there. Any help you might be able to offer would be appreciated. Thanks, Dave [Non-text portions of this message have been removed] ----------------------------------------------------------- To learn more about Freescale Microcontrollers, please visit http://www.freescale.com/mcu SPONSORED LINKS Intel microprocessors Pic microcontrollers 8085 microprocessor ________________________________________ YAHOO!
