FAX Error Code Listing

Table 29. Fax Error Codes

Value	Description and Suggested Action
EFX_BADIOTT	Invalid data in DF_IOTT entry. No data sent. Use ATFX_BADIOTT( ) to return a pointer to the DF_IOTT entry with invalid data. Verify that the appropriate Phase D continuation value is used. For example, an error occurs if the DF_IOTT entry specifies DFC_EOP but it is not the last entry in the table.
EFX_BADPAGE	Invalid or missing TIFF/F PageNumber tag. No data sent. Use ATFX_BADPAGE( ) to find the page offset from the first page described by the DF_IOTT entry.
EFX_BADPARM	Invalid value for fax parameter.
EFX_BADPHASE	Unexpected Phase transition (internal).
EFX_BADSTATE	Invalid initial state value specified. Following T.30 protocol, the initial state of the caller station must be transmitter (DF_TX) and the initial state of the called station must be receiver (DF_RX). See fx_initstat( ).
EFX_BADTAG	Incorrect values for TIFF/F tags. No data sent. Use ATFX_TFBADTAG( ) to return the tag number associated with the invalid tag value.
EFX_BADTIF	Incorrect TIFF/F format. No data sent. Verify that the TIFF/F file contains all mandatory TIFF/F tags (or subset). Use ATFX_TFNOTAG( ) to return the number of the missing tag. You can select the level of TIFF/F tag checking by setting FC_TFTAGCHECK in fx_setparm( ).
EFX_BADTFHDR	Bad TIFF/F header - incorrect values in fields. No data sent. Verify TIFF/F header values.
EFX_CMDDATA	Last command contained invalid data.
EFX_COMPAT	DF_IOTT entry problem. I/O file type, image width and resolution defined are not compatible with the receiver's hardware. No data sent. Use ATFX_BADIOTT( ) to return a pointer to the DF_IOTT entry that caused the error.
EFX_DSPERROR	DSP Fax resource error.
EFX_DISCONNECT	Fax call disconnected by other station. Use ATFX_ESTAT( ) to find out why disconnection occurred during a fax session. For example, some reasons may be receiver incompatibility or an invalid poll request by the transmitter.
EFX_DRVERROR	Error occurred in driver (internal).
EFX_FWERROR	Firmware error.
EFX_INUSE	Channel is in use (failed fx_open( ) or fx_close( ) using a DSP Fax resource).
EFX_INVALARG	Illegal argument to function.
EFX_INVALFUNC	Illegal call to function.
EFX_LIBERROR	Error in library state machine (internal)
EFX_MAXCHAN	Maximum channel capacity reached. Capacity varies by product. See Table 1. Key Fax Features and Specifications.
EFX_NODATA	Data requested is not available (NSF, DIS, DCS). A function is called before completion of the initial Phase B or the message was not sent by the remote station.
EFX_NOFAX	No fax capability on this device
EFX_NOMEM	Cannot allocate memory for more pages
EFX_NOPAGE	Requested TIFF/F page not found. Check the base page numbering scheme used.
EFX_NOPOLL	Poll not accepted. For example, if the transmitter issues a poll request and the receiver's poll bit is set to DF_NOPOLL, this error code is generated.
EFX_NORESOURCE	A DSP Fax resource is not available for assignment/sharing through fx_open( ).
EFX_NOSTATE	Initial state value not set
EFX_NOTIDLE	Channel is not idle. Some functions require that the channel be in idle state before invocation. Use ATFX_STATE( ) to determine the state of the channel.
EFX_NOTIMESLOT	No time slot assigned
EFX_NSFBUFF	Buffer length supplied to fx_getNSF( ) is less than 2 bytes
EFX_NXTCMDRX	Time out while waiting for next receive fax operation
EFX_RDFWER	Error reading firmware version
EFX_RETRYDCN	Disconnected after specified retries
EFX_UNSUPPORTED	Unsupported feature
