Unfortunately, we're out of serial ports on our system.  We only have 3.  1 goes to a modem, 1 is used for board-board comms, and the 3rd is the console port which we have shared w/ the diag port (eCos forces you to assign the diag port to a serial port and you can't assign it to /dev/null).

I can do ioctl w/ the FNONBIO flag to get it to run in non-blocking mode, but it only sees 1 in 18 characters (you hit the same key 17-18 times before one value gets to the read character function)-:
