                          WHat's V42bis? V32bis?

v.22bis = 2400bps

MNP4    = error correction

MNP    = compression

v42     = error correction (better)

v42bis = v42 + compression (better - in theory you can get 4X speed)

v32     = 9600bps

v32bis  = v32 + 12,000 + 14,400 + 7200 + 4800bps

     While  it  is  possible  to have  a  V32(bis)  modem  without  V42bis,
virtually all V32(bis) modems do also have v42bis, and all Zoom/modems with
V32(bis) do have v42bis.
