Because of a mail-server failure I lost the original query on the HST
protocal. However, quoting from a 1992 manual for the USRobotics High
Speed Modems:
"Under V.32 bis modulation, data flows at the same rate in both
directions. Under HST modulation, data flow is asymmetrical:
the high speed in one direction and 450 bps in the other. The
modems switch the fast and slow channels when the volume of data
flow changes. Interactive applications appear faster under V.32
modulation, while connection times are faster under HST modulation."

USR has a habit of creating thier own protocols. They
could screw up a
one-car funeral. Back in the BBS days I hated them passionatly.
Now that the real standards USR tried to undermine have become the
default, I have to say, thier modems are better than most cheapos in that
they are more flexible.
The USR Winmodem series (I call them Losemodems) are the worst pieces of
garbage ever foisted on the computer world. And I'm including the
Intellivision computer module in that appraisal.

Which HST protocol? AFAIK, there were at least
two; one 9600 bps and one
16800 bps flavour, as well IIRC a ~12900 flavour for mobile phones.
