1154 When using tty channel, put the serial port into raw mode (no echo, no
CR/LF conversion, no other line discipline/buffering).
sfurman 7723d 10h /or1k/tags/rel_17/
1153 When multiple interrupts were pending, e.g. TX buffer empty and RX
available, reading the UART's IIR register could potentially clear a
TX interrupt before it had been sent to the processor, thus dropping
the interrupt permanently.

Fix tested w/ both eCos and uclinux.
