Table 21. V.44/V.42/V.42 bis and MNP Data Modem Command Descriptions (Continued)

Command	Default			Description
		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)
+ER=m	0	Display messages when +ER = 1,
		+ER: LAPM		V42 LAPM protocol in use
		+ER: MNP 2		MNP 2 protocol in use
		+ER: MNP 2 4		MNP 2 and 4 protocol in use
		+ER: MNP 3		MNP 3 protocol in use
		+ER: MNP 3 4		MNP 3 and 4 protocol in use
