Challenge accepted :-)

Since I realised this would be useful for me (my firewall is a soekris
box with only a serial console), I fiddled around and came up with this:

7:23:respawn:/usr/bin/socat /dev/ttyUSB0,b19200,raw,echo=0
/dev/tty7,b38400,raw,echo=0

I'm not a socat expert, so there may well be better options to choose,
and I don't know that it actually needs to run from inittab (since it
won't quit each time you log out, unlike a getty), but it seems to
work :-)

Note that the machine I'm doing this on doesn't have a serial port, so
I'm using a USB-serial adapter, and it doesn't run X, so no conflict
on tty7.

And agreed - I don't know if it's the best way to do it.
