 Well I am very aware of the boards being wired for terminals, infact what I
did was to buy some RJ-45 --> DB-25 adapter kits and put them togeather for
the modems. Actually with a 1200 or 2400 baud modem they would work most of
the time, but with a Telebit Trailblazer Plus it was just a wasted effort,
and you could depend on having to reset the ICC card after every incomming
high speed connection.

 When you say it worked under DOS/Merge, do you maen that it worked with
standard ASCII terminals, or do you maen it supports a DOS oriented terminal
that generates scan codes ?? If you mean with an ASCII terminal, YES I believe
it would work, and you need to setup IXON in your gettydefs. I personally 
haven't used the DOS/Merge product, as I really want to avoid getting attached
to the Messy DOS software, and then get stuck with it's limitations..

 I really hate to say bad things about anybody's product, but I had several
sets of there boards here for many many months, and still to date they 
haven't fixed the problems. Now I just don't see why they sell a product
for UNIX, claim that it works perfect, when in reality everybody I know that
has run one has problems. When I called Microport and ask them which vendors
smart cards they recomended, and explained that I had a Bell ICC, they said
"Oh, you have an ICC from Bell Technoliges, We don't recomend you use that
board with our OS", so I suppose I should have called them before buying.
I use to have only the higest reguards for Bell Technoliges, as there tape
backups are of good quality, and I really hope they realize that they are
killing there reputation by selling a faulty product to the masses. I really
hope that they will get there act in gear (and I know they are listing, so
let's hear from you Bell!!)...
