during an error corrected data link.
\K0
Modem will immediately transmit a break character for a fixed time (300 ms) and
destroy any currently buffered data.
Same as the \K0 option, except all buffered data will be saved.
\K1
Modem will transmit a fixed time break character in sequence with the rest of the data
\K2
(default).
\K3
Modem will ignore all breaks received from the DTE.
Modem will transmit break characters in sequence with the rest of the data as long as
\K4
the DTE is transmitting this character.
\K5
Same as \K4 - required for compatibility with some communication software.
Sets the modem for private line or switched network lines.
Switched network mode.
&L0
&L1
2-wire private line mode.
Selects between asynchronous and synchronous operation in data mode. See the
%Vn command to select command mode format.
Selects asynchronous operation in data mode. See the \Nn command to select an
&M0
asynchronous protocol.
&M1
Selects synchronous operation in data mode. See the \Mn command to select a
synchronous protocol.
Selects the synchronous protocols that are available to the modem.
Selects normal synchronous mode.
\M0
\M1
Selects synchronous V.13, simulated controlled carrier, mode. Select transmit,
receive, or bidirectional with &En command.
Selects synchronous data compression mode. Modem must be configured for
\M2
internal transmit timing, and either Clock Stopping (\Q5) or Clock Throttling (\Q6) flow
control.
Controls MNP10 mode.
-M0
Disables MNP10.
Enables MNP10 Auto Reliable mode for central site operations (recommended
-M1
setting).
-M2
Enables MNP10 reliable mode (will not fallback to V.42/V.42bis).
