RE: [iPAQ] Twiddler2

The one at the site you listed that does PC to scancode would
probably work. The problem then would be a driver for the ipaq under
linux. I seem to remember someone mentioned a driver for a normal
keyboard via a convertor like this. Maybe someone else would have
details. The advantage to the one you build yourself is that it goes
to the special stowaway keyboard scancodes so you can use the
stowaway driver. Good luck and keep us up to date on your progress.
