[Bug 1244] - Failure to communicate with serial device

I got this to work using an ugly patch (see attached).  The write buffer
of the serial port was getting overrun.  That caused the app to wait for
an ACK packet that was never going to come.

What I don't understand is why the call to write() doesn't block until
the buffer has drained.
