You know this should be really easy to find but for some reason I am having no luck. First off, I'm a C programmer and I am really bad at reading Assembler code. I know there is a way to write a software UART for the 8051. I am using a Phillips P89C668 right now and I will be changing it to another soon. If someone could point me to some sample code how to setup a half-duplex UART I would really appreciate it. I have two pins and I am going to use one as tx and the other as rx. I don't think I need to do a full duplex but if there is something out there that does it I'll take it at this point! Thanks. -stv
