Hi Mastero,

Okay so you take this concept and have your first PIC send the request to the other PIC. I have a project going on where I have 20 PICs gathering alarm information and they simply send the data to a master board that displays the information on a display and then prints it out on a POS printer. I simply use SEROUT2 from the sending boards and monitor a "busy" line that tells the sender the line is clear and the receiver looks for the "busy" line to go low at which time is enters a SERIN2 routine. The receiver keeps the "busy" line low until the end user acknowledges the receipt of the alarm and then the receiver clears the busy line and awaits any new traffic.

Is this like something you are trying to do? I just thought that why would you have one PIC receive a command from a PC just to retransmit it to another PIC when one could do the whole thing and eliminate the middle man.
