 I think you are getting confused on this issue. I think the 33.6 modems
you mention are known as HSP (Host Signal Processor) which uses some of
the Pentium's power to drive it's card (probably to obtain the 33.6
connection speed instaed of 28.8). The modem has no UART connection
(makes the modem cheaper to make) so is set up through a software driver
device using COM 4.

 If you are using Turnpike to do your connecting you will find that it
probably wont even work. You have to set up a DUN connection through
win'95 and then switch to the Turnpike software once connected. The
people at Tunpike are aware these modems can cause and are currently
working on the problem.
