   Please remember that V.32 with MNP class 4 or LAP-M (V.42) enabled is *not* 
operating on a fundamental speed of 9600 bps but rather, thanks to the 
stripping of start & stop bits by the protocols, approaching an effective 
speed of (9600/8=)1200 CPS (minus some protocol overhead, natch).

   V.42bis is *data compression*.  If your data is already compressed (e.g. 
compressed newsbatches), you won't benefit from V.42bis.
