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
rpr=1
2.4.2.1 Receiver parameters are not reported; +FIS: and +FTC: reports are suppressed.
Receiver parameters are reported; +FIS: and +FTC: reports are generated.
tpr=0
tpr=1
2.4.2.1 Transmitter parameters are not reported; +FCS: reports are suppressed. (Note)
+FCS parameter is still loaded. Transmitter parameters are reported; +FCS:
reports are generated.
idr=0
idr=1
2.4.2.3 ID strings are not reported; +FTI:, +FCI: and +FPI: reports are suppressed.
ID strings are reported; +FTI:, +FCI: and +FPI: reports are generated.
nsr=0
nsr=1
2.4.2.4 Non-standard frames not reported; +FNF:, +FNS: and +FNC: reports suppressed.
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.
