Chapter 3 – Fax Class 2 Commands

Negotiation Reporting

Class 2.1

+FNR

 

 

Write syntax: +FNR=<rpr>,<tpr>,<idr>,<nsr>

Values:

0, 1 for each subparameter

Default:

0,0,0,0

 

 

 

+FNR is a compound parameter, used to control the reporting of messages

 

generated during T.30 Phase B negotiations. There are four switches, for four types

 

of reports:

 

 

 

 

 

 

Setting

Reference

Description

 

rpr=0

2.4.2.1

Receiver parameters are not reported; +FIS: and +FTC: reports are suppressed.

 

rpr=1

 

Receiver parameters are reported; +FIS: and +FTC: reports are generated.

 

 

 

 

 

tpr=0

2.4.2.1

Transmitter parameters are not reported; +FCS: reports are suppressed. (Note)

 

tpr=1

 

+FCS parameter is still loaded. Transmitter parameters are reported; +FCS:

 

 

 

reports are generated.

 

 

 

 

 

idr=0

2.4.2.3

ID strings are not reported; +FTI:, +FCI: and +FPI: reports are suppressed.

 

idr=1

 

ID strings are reported; +FTI:, +FCI: and +FPI: reports are generated.

 

 

 

 

 

nsr=0

2.4.2.4

Non-standard frames not reported; +FNF:, +FNS: and +FNC: reports suppressed.

 

nsr=1

 

Non-standard frames reported; +FNF:, +FNS: and +FNC: reports generated.

 

 

 

 

 

Note

 

 

 

If tpr=0, the negotiated image data format will not be reported. Without that report, the host must send

 

image data that is mandated by Recommendation T.30 (normal resolution, A4 length, 1728 width,

 

1-D coding) or it must enable the corresponding format conversion (+FFC). Otherwise, the data format

 

negotiated and the data format sent might not match, causing the facsimile session to fail.

Class 2

 

There is no equivalent parameter in Class 2.

Address & Polling Capabilities

Class 2.1

+FAP

Write syntax:

+FAP=<sub>,<sep>,<pwd>

Values:

0 (disabled) or 1 (enabled) for each subparameter

Default:

0,0,0

 

The +FAP subparameters allow the host to indicate the inbound subaddressing,

 

selective polling, and passwords capabilities to the remote station via the

 

corresponding bits in the DIS or DTC frames: bit 47 for SEP, bit 49 for SUB, bit 50 for

 

PWD.

 

These subparameters also control the reporting of those frames, if received. For

 

example, if the <sep> subparameter value is set to 0 (disabled), then the modem

 

ignores a received SEP frame; if the <sep> subparameter is set to 1 (enabled), the

 

modem reports the received frame using the +FPA: report.

Class 2

There is no equivalent parameter in Class 2.
