I have not tried this but the the system name you are calling should work.

Predictor-1 and Vj compression are enabled by default.  Vj compression
only compresses headers, not the data portion of the packet.  Predictor-1
compresses the entire packet.

In both cases, the other end of your link must support compression.

I turned off modem compression and enabled predictor-1 yesterday.  Ping
times to my next router went from 170Ms to 140Ms with a 21600 DCE link.
