Command Reference
Data Command Set - 55
Example: +EFCS: (0)
+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 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).
