Ouch.  I know how to check this in M$, but not in Linux.  Please teach me.

Will do and will advise.  Thanks.

This is the command that fires the wvdial program.  It's similar to 
something called xisp, the rpm for which I cannot seem to install 
because of a libforms.so.86 dependency.  I can --nodeps the rpm, but 
the program won't run without the right libforms package.

Wvdial is interesting.  When you initialize it the first time it probes the 
modem and reports a lot of interesting information.  It came up with an 
init string that isn't in my manual and I never heard of.  But it works.

Again, too logical for me to think of first.  ^^_^^  Will try, will advise.

Thanks!
