+ER - Error Control Reporting
This extended-format numeric parameter controls whether or not the extended-format "+ER: "
intermediate result code is transmitted from the modem to the DTE (see Section 3.5 and Table 3-15).
S95 bit 3 is reset to 0 for +ER=0 and is set to a 1 for +ER=1. The more recent setting of +ER
or S95 bit 3, and the W command setting, determines the actual error control result code
reporting (see S95 Parameter and W Command).
Syntax
+ER=[<value>]
Defined Values
<value> A decimal number corresponding to the selected error control option:
0 Error control reporting disabled (no +ER
intermediate result code transmitted).
1 Error control reporting enabled (+ER intermediate
result code transmitted). (Default.)
Reporting Current or Selected Values
Command: +ER?
Response: +ER: <current value>
Example: +ER: 1 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 +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 Values
<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 Values
<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.
