AT Commands for the MT5656ZDX, MT5600ZDX, MT5600BA/BL-Series Modems

Multi-Tech Systems, Inc. Commands Reference Guide (PN S000273D)

Command: +ER Error Control Reporting

Description: This extended-format numeric parameter controls whether or not the extended-format +ER:

intermediate result code is transmitted from the modem to the DTE.

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).

+ER=[<value>] +ER=[<value>] +ER=[<value>] +ER=[<value>]

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). (Default.)

1 = Error control reporting enabled (+ER intermediate result code transmitted).

Reporting Current or Selected Values:

Command: +ER?

Response: +ER: <current value>

Example: +ER: 0 for the default setting

Reporting Supported Range of Parameter Values:

Command: +ER=?

Response: +ER: (<value> range)

Example: +ER: (0,1)

Command: +ES Error Control Selection

Description: This extended-format command specifies the initial requested mode of operation when the

modem is operating as the originator, optionally specifies the acceptable fallback mode of

operation when the modem is operating as the originator, and optionally specifies the

acceptable fallback mode of operation when the modem is operating as the answerer. It

accepts three numeric subparameters:

Syntax: +ES=[<orig_rqst>[,<orig_fbk>[,<ans_fbk>]]]

Defined Values: <orig_rqst> Decimal number which specifies the initial requested mode of operation when

the modem is operating as the originator. The options are:

0 Initiate call with Direct Mode.

1 Initiate call with Normal Mode (also referred to as Buffered Mode) only.

2 Initiate V.42 without Detection Phase. If V.8 is in use, disable V.42 Detection Phase.

3 Initiate V.42 with Detection Phase. (Default.)

4 Initiate MNP.

7 Initiate Frame Tunneling Mode when connection is complete and Data Mode is entered.

<orig_fbk> Decimal number which specifies the acceptable fallback mode of operation

when the modem is operating as the originator.

0 LAPM, MNP, or Normal Mode error control optional. (Default.)

1 LAPM, MNP, or Direct Mode error control optional.

2 LAPM or MNP error control required; disconnect if error control is not established.

3 LAPM error control required; disconnect if error control is not established.

4 MNP error control required; disconnect if error control is not established.

<ans_fbk> Decimal number which specifies the acceptable fallback mode of operation

when the modem is operating as the answerer.

0 Direct Mode.

1 Error control disabled, use Normal Mode.

2 LAPM, MNP, or Normal Mode error control optional. (Default.)

3 LAPM, MNP, or Direct Mode error control optional.

4 LAPM or MNP error control required; disconnect if error control is not established.

5 LAPM error control required; disconnect if error control is not established.

6 MNP error control required; disconnect if error control is not established.

Reporting Current or Selected Values:

Command: +ES?

Response: +ES: <orig_rqst>,<orig_fbk>,<ans_fbk>

Example: +ES: 3,0,2 For the default setting.

+ES: 6,0,8 For V.80 Synchronous Access Mode originator and answerer.

Reporting Supported Range of Parameter Values:

Command: +ES=?

Response: +ES: (<orig_rqst> range),( <orig_fbk> range), (<ans_fbk> range)

Example: +ES: (0-4,6,7),(0-4),(0-6,8,9)
