I wish to add a remote buzzer for a Palm. Connection would be to
the cradle, with the cradle plugged into the USB and the palm in the
cradle. Buzzer would have its own driver and power.

Is there a slick and easy way of toggling one of the I/O lines
when the alarm goes off?

If it is a drudge task (download compiler, try to install compiler,
try to run compiler ... wreck cradle socket ... blow up Palm ...)
I can most likely struggle through. I have the Palm OS book and
can, I am sure, find the pinouts and I/O assignments on the web.

This would require programming on both the Palm and the desktop PC
that the USB is connected to.

You can't do a direct connection to another device via USB in the
current Palm devices. USB hardware can be either master (PC, Mac) or
slave (Palm, printer). The current Palm hardware is slave. Even if
it were master, the buzzer end would need a USB decoder chip and some
programming to make it respond to signals from the Palm.

Could I interest you in an old-fashioned Palm with a serial port for
$30 (Fry's, Ebay, computergeeks.com, surpluscomputers.net)?

Serial is relatively easy to interface to other hardware.
