	Most phone lines have a band-width of about 10Khz, so 9600 bps will
probably be the next standard after 2400.  There are modems out that are
supposed to do better than 9600 (not including compaction), but when you
get that fast, it all depends on the phone line.

	In terms of getting a faster modem, I personally have a 2400 bps
modem.  There are quite a few dialups (well, at least 30 going into UCB) that
run at 2400.  A standard may come in the near future for 9600, but I don't
think the 9600 bps modems will become 'common' for another couple of years.

	The difference between 1200 and 2400 bps is quite astounding when
you are trying to do serious work over a modem.  Most 2400 bps modems
also support 1200 and 300, of course.

	300 bps modems use 300 baud FSK.
	1200 bps modems use 600 baud & 2 phases of the waveform
	2400 bps modems use 600 baud & 4 phases of the waveform

	Once you get beyond 4 phases you have to get fancy... even at 2400
bps you are almost required to use an intelligent microprocessor (most modems
use microprocessors anyway) to continuously adjust the line filters.  If you
ever looked at 2400 bps on an oscilliscope, you'd know what I mean.
