I would like to be able to send and receive serial data in the background while running a main program on an SX in the foreground.  I know that this can be done in assembly using virtual peripherals.  I know also that this is not a built-in capability of SX/B.  However, I would like to add an interrupt driven background UART capability to my SX/B programs!  :smile: 

   The most obvious question to ask is, "[I]Has anyone already done something like this[/I]?"  If no one has then I may be naive enough to begin to attempt it myself.

   What I think might work is to modify either the "Dual UART Virtual Peripheral Implementation" code or the "Easily Implement UART Capabilities" code (both found on Parallax's SX [URL=http://www.parallax.com/sx/downloads.asp]downloads[/URL] page) in the hopes of making it "play nicely" with the rest of my SX/B programs.

   Does anyone have any insightful comments about this possibility?
