"When buying a telephone modem for your Linux box, don't
just grab whatever is selling for cheap at your corner BEST BUY.
Getting the correct type of modem will minimize your headaches and
improve your chances of a painfree installation. In Part 3 of
our Going Linux series, we give some basic guidelines for choosing
a Linux modem intelligently and cover some basic configuration
"The Signal Ground team continues it's Going Linux series with
another article aimed squarely at the newbie experience. Choosing a
telephone modem for your Linux box isn't the hardest thing you'll
ever do, but going into the purchase with the some basic knowledge
will certainly help you avoid the most common problems. In this
article, we'll discuss the basic type of modems to look for and how
to configure them. Finally, we'll describe our own experience with
a v.90 modem from AOpen."
"The most basic telephone modem to consider should be capable of
running the ITU v.90 protocol. This means that the modem supports
56Kbps downstream speeds and 33.6Kbps upstream speeds. In the USA,
while v.90 is capable of achieving 56Kbps, the FCC limits this to
53Kbps because of noise considerations. Preliminary specs like X2
or K56Flex have been superceded by the now-ratified v.90 spec, and
that is the spec supported by the vast majority of ISPs now."
