Writing to a serial port compilicates things a bit since one has
to insure that it's parameters are set correctly (e.g. baud rate,
parity, etc.) -- something like:

        stty 9600 cs8 -onlcr clocal < /dev/tty1a

The stty command allows you to set how the end-of-line stuff is
handled as well, and can be used to automatically supply CRLF.

Government is actually the worst failure of civilized man. There has
never been a really good one, and even those that are most tolerable
are arbitrary, cruel, grasping and unintelligent.
