In version 0.89pre7, which I'm about ready to release in the next
few days, there's a whole set of MWKEY_ values that the
keyboard driver, specially written for each PDA, can return.
Then, you just use the normal keyboard select mechanism,
using GR_EVENT_TYPE_KEY_UP|DOWN, and
you'll get a keystroke every time a button is pressed or
released.
Century Software is writing an iPAQ and YOPY keyboard driver,
with more coming shortly. You might want to hack a Helio
driver, basically, it opens up the /dev/xxx device and when input
is ready, the main Microwindows select() loop calls the driver, which
reads the hardware-dependent bytes and converts them to MWKEY_*
values that are then sent up the system...
