I've been thinking about using the serial port. Designing a new
hardware peripheral wouldn't be a good idea. But I have been thinking
about ataching a mouse to it. Then, I would simply modify moused to
catch mouse buttons and make it call 'halt' or 'reboot'.

I don't think it will be very difficult, cos it will be useful.

What do you think?

P.S. Note that I don't need high security in this way, because the
router is acting at home... so no need to worry.
