make sure you boot your unit up before you try to use this one, since it doesn't emulate that initial handshake with the 8051 -- I can work on that later probably...
The code for the keepalive and initialization of UART2 is in loader.c -- should probably be moved to shoehorn.c
oh yea, I've got images uploaded but I dont think they've booted yet ;)
