Ah yes - read the manual! Now there is a bright idea! I guess I overlooked this
earlier because my modem didn't actually come with any paper documentation -
but looking over it again, I found some online documentation buried with all
the windows applications that did offer some clues. I discovered how to get the
modem to report the actual connection speed instead of the serial-port speed (I
believe the factory configurations that I was using are acceptable). I seem to
be connecting at either 21.6 kbps or 24 kbps which is at least consistent with
the user data rates I was seeing. The bad news is that if I pull out my V.90
and plug in my old v.34 33.6 modem I get exactly the same connection speeds.
I've now tried changing slots in my computer and calling various other ISPs
around town (just to see if I can connect with their servers at
a higher rate) but I always get the same nasty slow connection. Attempts to
force higher connection speeds through configuration registers won't connect on
either my new modem or my old.
Unless anyone else has some bright ideas, I'm about ready to declare my home
phone wiring to be the worst in the west, return my 56K modem to compUSA, plug
back in the old 33.6, and start saving for a cable modem....
Thanks for you help - Jon
