At Commands For Fax; At+Fbadlin Bad Line Threshold - Siemens TC37 Module At Command Reference

AT Command Set

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
capabilities, both the current setting and the range of services available. This is provided by the
AT+FCLASS command (see pg. 45).
Note: When sending a FAX with a standard FAX application for Personal Computers it is
recommended to use Autobauding (AT+IPR=0).

applicable to the ME.

then the copy quality is unacceptable. If <badline> * 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.
