Sorry. When I glance at my e-mail but I'm not at home, I use my ISP's web
interface. It's clunky but it's the only way to get out a quick response (when
I'm not too busy at work).

What about that daisy wheel? :-)

Probably at http://www.ieee.org.

That way? Maybe ... but I wouldn't count on it. Don't forget you have to
have the shunt be well matched voltage wise. If it's too low, you've dragged
down your signal to prevent comms with the printer. Too high and you'll have no
effect. An even when you're properly matched, you've got a zener junction
voltage to overcome to have an effect. Ultimately, you may clamp down on
voltage spikes due to switch bounce but there may be sufficient current flowing
to create signalling. Ultimately, this seems like an awful lot of trouble for
very little benefit. I may be an engineer who likes fooling with computers but
this ain't worth the trouble. Try the mechanical switch. If it doesn't work,
try something else.
