Error Control Reporting: Controls whether the “+ER:” result code is transmitted from the DCE to the
DTE once a connection has been made. If enabled the result code displayed shall represent the current
negotiated DCE-DCE error control type and is issued after the Modulation Report (+MCR and +MRR) and
before the final result code Data Compression Report (+DR:). +ER accepts one numeric parameter
decimal value and the format is as follows:
0 Disables error control reporting (no +ER intermediate result code transmitted)
1 Enables error control reporting (+ER intermediate result code transmitted)
