Command: +ETBM Call Termination Buffer Management
Description: This extended-format compound parameter controls the handling of data
remaining in modem buffers upon call termination. It accepts three numeric
subparameters:
Default: None
Defined Values: <pending_TD> Decimal number 0 specifies disconnect will occur
immediately and all buffered transmit data will be
discarded when the local DTE requests call
disconnection.
<pending_RD> Decimal number 0 specifying that disconnect will occur
immediately and all buffered receive data will be
discarded when the local DTE requests call
disconnection.
<timer> Decimal number 0 specifying that the modem will not
attempt to deliver the buffered data before abandoning
the attempt and discarding remaining data.
Report Commands: +ETBM? Reports Current or Selected Values.
Response:
+ETBM: <pending_TD>,<pending_RD>,<timer>
Example: +ETBM: 0,0,0
+ETBM=? Reports Supported Range of Parameter Values.
Response:
+ETBM: (<pending_TD> range),(<pending_RD> range),
(<timer> range)
Example: +ETBM: (0),(0),(0)
Command: \B Transmit Break to Remote
Description: 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 in conjunction 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.
Defined Values: 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.
