Mark,
The typical reason for failure is under IE5.0 is a security exception is
being
throw. To my knowledge, javax.comm has problems being run under IE. It's
been a long time since I've done any work with the browser JVM, so I may
be incorrect. Someone else on the list may be able to shed some light on
the
issue. My best guess is to make sure you've signed the cab file with the
highest permissions so that it can do System.loadLibrary.
I'll check with some other people here and see if I can get any other
information.
Thanks,
Clayton Ware
