Updating KLN 94 - Parallels Mac OS X

Hi

Has anyone been successful in updating a Honeywell Bendix-King KLN 94
(or 89/B) database via "direct cable connection" from the computer to
the KLN94's serial port using an Intel Apple Mac running Windows under
Parallels? The Mac doesn't have a serial port so it is necessary to use
a USB serial adapter.

I'm particularly interested in knowing precisely what USB serial adapter
you used and with which build of Parallels.

I have tried with a Keyspan USA-19HS, both using the Windows XP drivers
and via a socket to the OS X port without success. Honeywell BK list a
Belkin F5U 103 and iConcepts 60446 but neither of these are readily
available here in Australia.

I realise this sounds weird (and maybe too ambitious), but the Honeywell
BK GPS Database Loader is the last remaining problem to be solved before
I ditch my old laptop.

Thanks in advance
Andrew/.
