You will only get 33.6 k if everything is correct like line quality for 
example.

That is what is expected at present. There is a known difficulty between
some USR modems and Demons ascends at 33.6.

Yep that's the problem.

Yes that is typical as well. The slower part may be nothing to do with
modems. The first batch of lines were at one stage reported as being
more congested than the Colts.

They should have told you to use S33=32 in your dial up string. That 
disables the 3429 symbol rate and confines connections to a maximum of 
31.2 k (check your USR handbook to make sure it is the same as mine). 
Since I added that I get a 99% reliable connection at 31.2.

No - but it has been fairly flogged to death. Perhaps either USR or 
Demon or someone will eventually find a palliative.

Yes - see above but they are not *my* ideas

The signature separator should be "-- " [hyphen, hyphen, space] and then
your signature will be automatically dropped in replies (at least with
Turnpike). As you seem to be using Turnpike 3.01 like me, you must have
altered it from the default setting?
