It also serves to wake up your pilot if it is off. I don't know about
the V series, but my IIIx has a maximum of 3 minutes before automatic
shutoff.

One approach to this would be to use one of the unused RS-232 control
lines to switch on a transistor or opto-isolator wired across the
hotsync push-button. Then you would have to hack the pilot-link library
to raise this line when a hotsync is desired. I don't imagine that
would require very much programming.
Looking at http://www.public.iastate.edu/~jdwhite/palm/PCPD-serial.html
if you are Real Brave you might be able to get away with connecting DTR
on the PC directly to GP1 terminal on the pilot. I would at least use a
diode and the largest possible resistor in series to be on the safe side.
This is irrelevent to your Vx, but anybody following this who has a
non-rechargeable pilot should be aware that leaving it in the cradle
for a long period of time can significantly reduce the AAA cells' lives
as the pilot sends a fair amount of current into one of the RS-232
handshake lines whenever it is in the cradle.
