V.34 is the data communication protocol while v.42bis negotiates the data 
compression.  USR's modems will display all this information on one line 
while Rockwell's can be made to show this information on multiple lines.  
Sierra's chipset modems might have a command to display the equivalent 
information but I haven't had much experience with them so can't help you 
there.  The 24000 bps speed basically says that you have a v.34 connect.

Sierra no longer manufactures modem chipsets and all information on them has 
been removed from their web page.  One friend of mine purchased a laptop that 
had a built in Sierra chipset modem which managed a massive 2 paragraphs in 
the excuse for a manual so I spent some time looking for information with no 
results.  Perhaps you might have better luck with Toshiba.
