Command: \K
Break
Control
Description:
Controls the response of the modem to a break received from the DTE or
the remote modem or the \B command. The parameter value, if valid, is
written to S40 bits 3, 4, and 5.
Defined Values:
The response is different in three separate states.
The first state is where the modem receives a break from the DTE
when the modem is operating in data transfer mode:
\K0 Enter on-line command mode, no break sent to the remote modem.
\K1 Clear data buffers and send break to remote modem.
\K2
Same
as
0.
\K3 Send break to remote modem immediately.
\K4
Same
as
0.
\K5 Send break to remote modem in sequence with transmitted data.
(Default.)
The second case is where the modem is in the online Command State
(waiting for AT commands) during a data connection, and the \B is
received in order to send a break to the remote modem:
\K0 Clear data buffers and send break to remote modem.
\K1
Same
as
0.
\K2 Send break to remote modem immediately.
\K3
Same
as
2.
\K4 Send break to remote modem in sequence with data.
\K5 Same as 4. (Default.)
The third case is where a break is received from a remote modem
during a non-error-corrected connection:
\K0 Clears data buffers and sends break to the DTE.
\K1
Same
as
0.
\K2 Send a break immediately to DTE.
\K3
Same
as
2.
\K4 Send a break in sequence with received data to DTE.
\K5 Same as 4. (Default.)
Result Codes:
OK
Otherwise ERROR
Command: -K
MNP
Extended
Services
Description:
Enables or disables conversion of a V.42 LAPM connection to an MNP 10
connection. The parameter value, if valid, is written to S40 bits 0 and 1.
Defined Values:
-K0 Disables V.42 LAPM to MNP 10 conversion. (Default.)
-K1 Enables V.42 LAPM to MNP 10 conversion.
-K2 Enables V.42 LAPM to MNP 10 conversion; inhibits MNP Extended
Services initiation during V.42 LAPM answer mode detection phase.
Result Codes:
OK
ERROR
