-> JF>No offense, but that simply isn't true.  USR's terbo is fully
-> compatible
-> I never said it wouldn't work in the lower speed.
You may not have said it, but you certainly implied it, and you've made
no effort to correct that misconception among the unfortunate readers of
this echo who might have been mislead by your remarks.
USR's terbo is fully compatible with AT&T's terbo.   Period.
-> USR created the 21k version of v.32terbo, and that's all they did.
-> They publicized it etc. as if they had created the whole thing,
Really??   Perhaps you would care to read this excerpt from the 1993 USR
press release which describes the addition of the feature.

U.S. ROBOTICS ADDS SEVEN NEW PRODUCTS TO COURIER MODEM LINE;
PRODUCTS OFFER 10 NEW FEATURES INCLUDING 21.6 KBPS CONNECT SPEED
New Courier Modems Offer Host of New Features Including V.32 terbo,
HST Cellular, V.17, Security; Products to Ship September 1, 1993
SKOKIE, Ill. -- August 23, 1993 -- U.S. Robotics, Inc. today announced a
major evolution to its Courier modem line; the company will ship new
Courier models beginning September 1 that include a battery of new
features, most notably the 19.2 Kbps V.32 terbo protocol and U.S.
Robotics' proprietary Adaptive Speed Leveling (ASL[tm]) technology,
which further boosts speed to 21.6 Kbps.  The new features fall into
three broad categories:  increased data rates, fax enhancements and
high-end features. The company is offering an upgrade program for
current Courier high-speed modem users, also beginning September 1.
U.S. Robotics Among First To Ship V.32 terbo
Among the features included in the new modems is V.32 terbo, a new
protocol for 19.2 Kbps data transmission developed by AT&T; Courier
modems will be among the first shipping products to include V.32 terbo,
which delivers a 33 percent increase in speed over the 14.4 Kbps V.32
bis standard.  The move to V.32 terbo is in keeping with U.S. Robotics'
philosophy of developing modems that support a variety of protocols and
provide compatibility with a wide range of modems from other vendors.
These products allow Courier customers to take advantage of increased
data rates, while still assuring them of a clear upgrade path to the
forthcoming V.fast standard.  Additionally, the new modems provide
Courier customers the added benefit of proprietary technology that
boosts connect speed to 21.6 Kbps.
Proprietary ASL Increases Speed to 21.6 Kbps; DTE Interface Rate Jumps
to 115.2 Kbps
The Courier V.32 terbo modems include the company's proprietary Adaptive
Speed Leveling (ASL[tm]) protocol, boosting throughput to 21.6 Kbps, a
50 percent increase in speed over the current 14,400 bps V.32 bis
standard. This protocol allows users who are connecting two Courier
modems to take advantage of the 21.6 Kbps rate; V.42 bis data
compression provides an additional increase in throughput.  An increased
DCE to DTE (modem-to-computer) interface rate of 115,200 bps and faster
processors accommodate these higher speeds.

Courier Modems Still Upgradable to V.fast (ITU-T V.34)
Dale Walsh, U.S. Robotics vice president, advanced development, and a
member of the ITU-T committee developing the V.34 standard, points out
that V.32 terbo should not be confused with the V.fast standard.  "The
V.32 terbo protocol is really an extension of V.32 bis," said Walsh.
"In fact, when you compare the processing power necessary to run V.32
terbo and V.34, the processors in V.32 terbo modems are more like the
processors used for V.32 bis -- they are certainly not capable of
achieving the 28.8 Kbps throughput that will be available with V.34."
...
...
The full list of features that will be added to the Courier line
includes:
Data Rate Enhancements:
*  V.32 terbo
     Supports data rates of up to 19.2 Kbps.
*  Adaptive Speed Leveling (ASL*) for 21.6 Kbps throughput
     Exclusive to U.S. Robotics; proprietary protocol boosting connect
     speed to 21.6 Kbps
*  Increased DTE interface rate of 115.2 Kbps

Where is the part about USR acting "as if they had created the whole
thing"?  I sure don't see it.   I do see USR giving credit to AT&T,
though.   This press release states in plain English that it was AT&T
that created terbo, and that USR's 21600 extension is a proprietary
feature.   Nowhere does USR claim credit for anything but the 21600
extension, nowhere does USR claim that the 21600 extension works with
other manufacturer's modems, and I challenge you to provide an example
of anything to the contrary.
Your revisionist history is almost on par with Richard's, keep up the
good work.
