AT Command Reference

Error Control Selection Command (+ES)

Syntax

+ES[=[<orig_rqst>[,<orig_fbk>[,<ans_fbk>]]]?=?]

Description

This extended-format compound parameter controls the manner of operation of the V.42 protocol on the PSTN link between the Gateway IWF and the host modem (if provided in the IWF). It accepts three numeric sub-parameters:

<orig_rqst>

Specifies the initial requested mode of

 

operation when the IWF is operating as the

 

originator.

<orig_fbk>

Specifies the acceptable fallback mode of

 

operation when the IWF is operating as the

 

originator.

<ans_fbk>

Specifies the acceptable fallback mode of

 

operation when the IWF is operating as the

 

answerer.

As shown in the syntax above, any of <orig_rqst>,

<orig_fbk> or <ans_fbk> may be optionally specified. If any parameter is left unspecified, its value is left unchanged. If all values are left unspecified then all are reset to their power-on default values.

Optional parameters must be separated by commas. The commas act as place holders (in the command parser) for the missing optional parameter.

+ES? queries for the current parameter value settings.

+ES=? queries for the acceptable parameter ranges.

Valid Value(s)

<orig_rqst>:

0Direct mode.

1Initiate call with Buffered mode only.

2Initiate V.42 without Detection Phase. If V.8 is in use, this is a request to disable V.42 Detection Phase.

3Initiate V.42 with Detection Phase.

4Initiate Alternative Protocol.
