I have a SupraExpress 56i v.90.  It came with a bunch of jumpers on it
which allowed me to take the modem out of PNP mode and "hard wire" it to
use a particular COM port.  If you still have the documentation for the
modem, it may tell you how you can change the modem settings.  If you
don't have the documentation, go to Diamond's web site ( ) and search for modem documentation.  It
should be there somewhere.  I know I was able to find some documentation
for my modem before but I can't remember the specific URLs.  I do
remember that they had support for a wide variety of modems, not just
the 56k ones.

Good luck,


1. Problems with PPP, connection 'dying' away ...

I'm trying to connect to my ISP (using a dynamic IP) under KDE,
everything works fine, I connect with kppp, log in, start the PPP
session, then I can even request one (but one) page in a browser and
then the connection 'dies' away until I get the 'daemon died
unexpectedly' message ... I really dont know what could be wrong in my
configuration (perhaps the DNS-configuration?). Strange is that when I
do not try to send or reveice data, the connection stays, only to be
taken down by the ppp-daemon when I request information.

(working on this problem for hours now ;)
