   US Robotics Courier V.32 (and V.32bis) modems add an additional feature 
while continuing to be fully V.32 (and V.32bis) compliant.  This is the 
ability to negotiate the speed in the transmit and receive directions 
separately.  This is of course only available when two Courier modems are 
used.  This is nice because the noise in one direction and the resulting 
slowdown doesn't effect the other direction.

   I have had long distance phone conversations where one person could hear 
noice that the other couldn't. 

   I assume this was developed because of USR's knowledge of asymmetric 
communications that their HST modems use.  This makes purchasing USR's 
modems a good choice IMHO.
