MNP/V.42/V.42bis commands
Command Function
%C_ %C0 Disable MNP Class 5 and V.42bis data compression
%C1
Enable MNP Class 5 data compression only
%C2 Enable V.42bis data compression only
%C3 Enable MNP Class 5 and V.42bis data compression
&Q_ &Q0 Direct data link only (same as \N1)
&Q5 V.42 data link with fallback options
&Q6 Normal data link only (same as \N0)
\A_ \A0 64-character maximum MNP block size
\A 1 128-character maximum MNP block size
\A2 192-character maximum MNP block size
\A3 256-character maximum MNP block size
\Bn Send a 1/10 second line break to the modem, where n = 1 to 9.
At normal connect, the default is
3
\Kn
Set break control, where n= 0 to 2. The effect of this command
depends on the modem operating condition.
Default is 1.
\N_ \N0 Normal data-link only
\N1 Direct data-link only
\N2 V.42 or MNP data link only
\N3 V.42/MNP/Normal data link
\N4 V.42 data link only
\N5 MNP data link only
