The US Robotics [marketing] employee who wrote that article could hardly
be called an unbiased source of information... He didn't mention a few
of the nice advantages of competing technologies, or disadvantages of
his own...

1) V.32 modulation is simply not as robust as PEP in the real world. PEP
	gets much higher data rates on real world impaired lines most of
	the time. An disadvantage of both V.32 and USR techniques.

2) PEP gets much more than 9600 baud on good lines, even without data
	compression. An advantage for Telebit.

3) USR HST modems simply don't connect at high speed on slightly impaired
	lines. I had *lots* of trouble with a semi-local connection
	between Cupertino and Palo Alto... about 10 miles away, and we
	aren't exactly in a telephone service backwater! :-(

Some of his information is simply untrue... The current PEP protocol does
not have a "several second" response time delay for typed characters; it
isn't truly instant, but it is very good!

Am I biased? Probably- I've used both HST and PEP modems, and PEP modems
win hands down in the real world. It is hard to be unbiased!
