Jim, thanks! That should do fine (and no need for me to fiddle deep in the
hardware). Any reason this call ISN'T documented? Seems to be a very useful
feature for those of us developing hardware add-ons to be able to check the
status of the GP2 pin.
Now of course you have no obligation to answer and I know it might change
in the future, but do you know what the difference is between the
hwrDockStatusModemAttached and the hwrDockStatusDockAttached flags? Do they
both refer to pin GP2 or two different signals? I know that on a Palm V the
voltage level driven on GP2 (called "I2" on the V) indicates what type of
device is connected: charger or modem. But what is a generic "dock"? Is it
set when anything other than nothing is detected? Hmm.
Regards,
Kris
