I need to communicate between a program running on an A780 (presumably a java app written in the SDK) and an external 3.3V serial device. I know the EMU can be switched to a UART mode, but is there an easy way to do this? For instance, is there some way I can do this once at a terminal logged in as root? It sounds right now like it requires recompiling the kernel. Failing any good solution, I might just crack the phone open and solder wires to the FFUART pads, but I'd rather not do that.

Also, could someone assure me that the java SDK won't make sending and receiving data over the UART painful?
