AT*V Maximum V.42bis Dictionary Size
The V.42bis dictionary size is normally negotiated during the V.42 handshake.
The Telenetics Global Carriers have enough memory to store 8,192 dictionary entries. This will
allow 8:1 compression on some file types.
Some modems do not correctly negotiate the dictionary size, in these cases the user should
reduce the dictionary size to 2,048 entries (4:1 compression ratio).
If the remote modem exhibits wrong negotiation the user will see corrupted data and/or sudden
disconnection.
