+ER: <value>
Syntax
+ER=[<value>]
Defined Value
<value> A decimal number corresponding to the selected error control
option:
0 Error control reporting disabled (no +ER
intermediate result code transmitted). (Default.)
1 Error control reporting enabled
(+ERintermediate result code transmitted).
Reporting Current or Selected Values
Command:
+ER?
Response: +ER: <current value>
Example: +ER: 0 for the default setting
Reporting Supported Range of Parameter Values
Command:
+ER=?
Response: +ER: (<value> range)
Example: +ER: (0,1)
+ER: <type>
The +ER: <type> reported represents the current (negotiated or renegotiated)
modem-modem error control type. If enabled, the intermediate result code is
transmitted at the point during error control negotiation (handshaking) at which
the modem has determined which error control protocol will be used (if any),
before the final result code (e.g., CONNECT) is transmitted. The format of this
result code is:
The +ER intermediate result code, if enabled, is issued after the Modulation report
(+MCR and +MRR) and before the Data Compression Report (+DR).
Syntax +ER: <type>
Defined Value
<type> An alphanumeric code corresponding to the selected protocol.
NONE Error control is not in use.
LAPM V.42 LAPM protocol is in use.
ALT MNP is in use.
Example
+ER: LAPM
+ETBM - Call Termination Buffer Management
This extended-format compound parameter controls the handling of data remaining
in modem buffers upon call termination. It accepts three numeric subparameters:
Syntax
+ETBM=[<pending_TD>[,<pending_RD>[,<timer>]]]
Defined Value
<pending_TD> Decimal number 0 specifying that 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
