I don't know whether or not Datapack III+ operates in the 2mhz mode,
but I suspect it does, and if so, that may be the culprit.  I've heard
a number of complaints about the RS-232 pak which were eventually
traced to the 6551.  Many of the older paks had 6551's which won't
work with the 2 mhz clock rate.  If yours is one of these, the
simplest fix is to replace the whole pak (if you can find one!), or at
least the 6551.  I'm not sure if that's your problem, but I have heard
about this happening.  If it works fine under programs such as
Mikeyterm, or the built-in comm program, then that is probably the
problem.  Try using the program built-in to the pak, (or any other
comm program which doesn't know about the 2 mhz clock.  Greg-e-Term,
for example, may use the fast clock on the 3) just to see if
everything works.  If so, then it may well be the clock speed that's
hurting you.
