3 AT Commands for FAX

The following commands can be used for FAX transmission.
If the ME is acting as a Fax-Modem to a PC-based application (e.g. “WinFax“) it is necessary to select
the proper Service Class (Fax Class) provided by the ME. The ME reports its Service Class capabili-
ties, both the current setting and the range of services avaible. This is provided by the AT+FCLASS
command (see pg. 42).
Note: When sending a FAX with a standard FAX application for Personal Computers it is recom-
mended to use autobauding (AT+IPR=0).

Currently defind Service Class values (see TIA/EIA-592-A)

3.1 AT+FBADLIN Bad Line Treshold

Read command

AT+FBADLIN?

This command defines the “Copy-Quality-OK”-threshold. If consecu-
tive lines have pixel count errors in normal resolution (98 dpi) mode, then the
copy quality is unacceptable. If * 2 consecutive lines have pixel count
errors in fine resolution (196 dpi) mode, then the copy quality is unacceptable.
“Copy Quality Not OK” occurs if either the error percentage is too high or too
many consecutive lines contain errors. A value of 0 implies that error checking
is not present or disabled.
