+ER:
The +ER: 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).
