Re: Redirect stdin & stdout to serial port

This is expected, because <> operator says to open for read/write on
descriptor 0. It doesn't say anything about stdout.

This is also expected, since ttyS0 was opened for reading, so you
can't write on it, even if you do attach it to stdout.
I think the solution might be a combination of both of Igor's suggestions
cmnd <> /dev/ttyS0 >&0
Ie, open the port read/write on stdin and then dup it to stdout.
Let me know if that works.
