Thanks Remo!! This worked great!!
We tested it on the following:
POSE/PalmOS 2.0 - works
POSE/PalmOS 3.0 - works
POSE/PalmOS 3.3 - works
POSE/PalmOS 3.5 - works
Visor Prism/ PalmOS 3.5.2H1 with 8MB module - works

This is basically what we were using (note the past tense :-).
Didn't work on POSE/PalmOS 2.0 for us.
