I ran into similar issues with PC based laptops. The update program simply doesn't like certain (if not most) USB-Comm port adapter/computer combinations. Honeywell claimed that you had to use certain USB-Comm port adapters, and I tried the one they recommended with no improvement.
The best solution I found was to use an older laptop with a standard comm port which has been working flawlessly through many update cycles. I'm using the latest version of the GPS Database Loader.

Updating the Honeywell KLN 94 GPS from a MacBook Pro is now working
with both Parallels 4 and VMWare Fusion with Windows XP using a
Keyspan USA-19HS USB-serial adapter.
IOGear USB and Prolific adapters have been tried without success.
(It is POSSIBLE to establish a connection at 9600 using a Prolific
adapter and a serial client utility to map the Windows serial port to
an OS X pipe, but that does not seem able to pass the control code
needed to increase the baud rate. At 9600 the update will take around
The key to the solution is the updated Windows XP drivers from
Keyspan, version 3.7S. These are obtainable from the Keyspan website.
The credit should go to Tom B. from KWDR, who first solved the mystery
with VMWare Fusion. After he alerted me, I also succeeded with
In case this might be useful to anyone, this was my experience:
1. Installed the Keyspan USA-19HS v3.7S drivers on Windows XP SP3 VM
under Parallels v4.0. This is the same driver file as used in Windows
2000. I did not install the OS X drivers, although Tom did in his
tests. I used the Honeywell Bendix King GPS Database Loader version
1.7. If you have tried this before with earlier versions of the
drivers, you will have noticed that the "internal loop back test" in
Keyspan serial assistant, which had previously frequently failed, now
2. Connected to KLN 94 and on first attempt, received error "Ready for
next diskette or data loader not ready" on KLN 94 after existing
database erased. Configuration was: COM 5 (auto assigned), default
Windows initial serial port settings, Com Port Adjustment 0. All
other settings default. My second attempt produced the same error.
For the third attempt, I experimented with values 5 and 10 for Com
Port Adjustment in the GPS Database Loader, but noted that these
precluded the successful switch from 9600 to 115200 baud, so reverted
to a value of 0. At this point, I changed the Mac's OS X System
Preferences for Energy Saver, Power Adapter, to "better performance"
and manually altered the display and computer sleep parameters to
sensible values (20 minutes and 1 hour 20 respectively). Using Device
Manager in Win XP VM, the COM 5 port defaults were set to 9600, 8
bits, 1 stop bit, odd parity and no flow control. Set Parallels to
always connect the Keyspan USA-19HS device to the VM. My purpose here
was to try and eliminate factors that might prevent receipt by GPS
Database Loader of the KLN 94's message that the database erase has
been completed and the transfer can commence.
3. I then started the Keyspan Serial Assistant and restarted the KLN
94 and Honeywell BK GPS Database Loader program.
4. Whilst running GPS Database Loader, I used Keyspan Serial Assistant
monitor to view comms between Mac and KLN 94. Observed nothing
untoward there, but noted longish pauses between changing focus
windows and moving between tabs in Serial Assistant. Nevertheless,
the update completed successfully, although there was no indication on
the GPS Database Loader program window of % status until completion.
The KLN 94 display incremented progress as expected.
5. Set "transmit completion timing advance" to "Faster" in Keyspan
Serial Assistant and then exited that program.
6. Restarted KLN 94 and GPS Database Loader program. Ran the latter
again, but this time without Keyspan Serial Assistant, without any
problems other than, as previously noted, progress indicator on the
GPS Database Loader did not move until the update completed at 100%.
The data transfer appeared to progress more quickly than usual, but I
did not keep timings.
I'm happy enough with the result to continue updating the KLN 94 from
the Mac now. I hope this is some help to other KLN 94 owners in this

Oooh another security now listener!
Yep, since the beginning.
I consider it a free graduate level course in personal computer
I used the adapter Honeywell suggested on a KLN 89/B and didn't have any problems. You must follow the button pushing sequence as prompted from the Dataloader.
