Overall Prolific doesn't have a good track record with either LInux or
Mac OSX - at least not in the context of users posting on APRS related
mailing lists.  Based on my own experience, Prolific is fine in Linux
for the GPS application - even a long road trip won't reproduce the
problem.  However, a 7x24 IGate is another story.  Prolific based USB
to serial adapter = 2-3 days of continuous operation followed by the
port freezing - reboot to recover it.  FTDI based USB to serial
adapter = no issues - runs for weeks.  No changes were made to any
other hardware or software.

Not surprisingly the adapters at the bottom of the price scale are
usually Prolific based.
