I am concerning buying a new modem to replace my old one.  I reviewed the
Computer Shopper and found out there are different kinds of 9600 bps
modems.  Several terms I don't really understand.  Can some one in the
net help me to figure out the meaning of these terms?

1. What does HST mean, and what are the differences between HST and
   V4.2?
2. Some modems are able to transmite in the speed of 19.2K if it is
   in COMPRESS mode.  What does the COMPRESS mode do when I transfer
   files?
3. Is there any standard amoung these high speed modems? Is there any  
   compatiable problems between modems? 
4. US Robotics modem has two different models, HST 9600 and Dual standard
   9600.  The price difference between these two models is about $300.0.
   What does DUAL STANDARD mean here?

Thanks in advance.
