I have implemented a crude patch to the pi_serial_open function of the
pilot-link package (which also affects pilot-link-libs) which does
just that.

At the moment it retries to open the port again after a 50 millisecond
delay for a total time of 5 seconds. It works quite well with my Visor
Platinum, and I expect it to work with the Prism and Edge as well,
since they all use Handspring's version of PalmOS 3.5.2.

The drawback is that it only says "Press the hotsync button now"
_after_ it has successfully opened the port. To change this all
applications would have to be changed, and I only changed enough to
just make it work. Start the syncing program (pilot-xfer e. g.), and
within 5 seconds, press the button on the cradle.

I hope it does not break hotsyncing with the older models (Visor and
Visor Deluxe).

I'd be glad if some more people (with both old and new Visor handhelds
and also Palm Inc. devices) could test the new pkg.

I attach the modified pkgsrc of pilot-link.
