After the modem review in the fall where PC Mag said the T2500 had trouble
passing data across impaired lines in PEP mode (remember the resulting
discussion here?), and the recent V.22bis modem review where three different
modems all registered ~230 cps transfer rate across 'average' phone lines
on a compressed file with an MNP5 connection, well...

I don't put my faith in PC Mag's test results.  Their articles are getting
better as far as having fewer technical mistakes, but I still entertain
doubts about their testing competence.

You asked for my opinion - you got it.
