\B - Transmit Break to Remote
In non-error correction mode, the modem will transmit a break signal to the remote
modem with a length in multiples of 100 ms according to parameter specified. If a
number in excess of 9 is entered, 9 is used. The command works with the \K command.
In error correction mode, the modem will signal a break through the active error
correction protocol, giving no indication of the length.
Syntax \B<value>
Defined Value
<value> Decimal number corresponding to the selected option.
1-9 Break length in 100 ms units. (Default = 3.) (Non-error
corrected mode only.)
Result Codes
OK If connected in data modem mode.
NO CARRIER If not connected or connected in fax modem mode.
Note: When the modem receives a break from the remote modem, break is passed
to the DTE as follows: In non-error correction mode direct, the break length is
passed; in non-error correction mode normal and in error correction mode, a 300
ms break is passed.
\K - Break Control
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.
Syntax \K<value>
Defined Value
<value> Decimal number corresponding to the selected option.
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:
0 Enter on-line command mode, no break sent to the
remote modem.
1 Clear data buffers and send break to remote modem.
2 Same as 0.
3 Send break to remote modem immediately.
4 Same as 0.
5 Send break to remote modem in sequence with
transmitted data. (Default.)
