While I had made the decision to share information gleaned during the testing of V.92 here at the University of Washington there was no intention of continuing to test modems or applications software and the page has become quite dated. As a result I've been forced to discontinue this listing. If you are associated with the UW, you may want to email help@cac.washington.edu for assistance. If you're non-UW and/or are looking for more recent data or support try:
..or a sig newsgroup such as comp.dcom.modems
I leave you with these thoughts...
1) Your most important diagnostic tool is yourself.
2) Support is usually best obtained from your ISP or the people
who made the modem.
3) There's more to it than just the modems at the ends of the
wire.
4) Many 'modem problems' are call-path problems. Try a dialing
different number for your current ISP.
5) Your circuit provider leases you a voice grade line.
If your can hear static, crosstalk, hum, etc. call 'em. Otherwise
it's usually a waste of time.
6) Where connect rates are concerned the best init string is either
no init string or one that caps the connect rate to 20% less than
the modem would typically connect at.
7) Before signing on to an ISP try dialing in to several to check
connect rates.
8) If you've already signed up and are having trouble, #7 can
also give insight if you are having a problem with #4.
Cheers!
