[comp.dcom.modems] Vadic 9600VP modems

Back in February there appeared a review of Vadic 9600 VP modems which
seemed reasonably fair. I would now hove to say that after 5 months
experience I could not reasonably recommend these modems to anyone
considering dialup high-speed capablilty. Reasons are:

1. The effective throughput with error correction enabled is closer
to 2400 bps (or less). With standard file transfer protocols such
as Kermit it is even less (to be fair, this is documented in the
manual, though not in the advertising).

2. Customer support is nearly non-existent. I have logged nearly
two hours of telephone "hold" time waiting for a tech support person
who never got on the line.

3. Most of the really useful parameters are NOT programmable from the
front panel. What IS programmable from the front panel is generally NOT
things that you are likely to change on a day-to-day basis. What this
means is that if you are hooked up to something like a multiplexor,
you are constantly having to disconnect the modem and attach to a terminal
in order to change simple settings.

4. The number of options that you are given is such that a trial and
error approach to option setting (which would make as much sense as
trying to glean something from the documentation), would have you testing
nearly 200 possible configurations (eliminating those that are clearly
not useful).

We have been dealing with Vadic products for nearly seven years but
never have I been so frustrated with a product or with a vendor's
lack of customer responsiveness as I have with this product.
