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 necessar y to select

the proper Service Class (Fax Class) provided by the ME. The ME repor ts its Service Class capabili-

ties, both the current setting and the range of services available. This is provided by the AT+FCLASS

command (see pg. 43).

Note: When sending a FAX with a standard FAX application for Personal Com puters it is recom-

mended to use autobauding (AT+IPR=0).

Read command

AT+FBADLIN?

This command defines the “Copy-Quality-OK”-threshold. If <badli ne> consecu-

tive lines have pixel count errors in normal resolution (98 dpi) m ode, then the

copy quality is unacceptable. If <badline> * 2 consecutive lines have pixel count

errors in fine resolution (196 dpi) mode, then the copy qualit y is unacceptable.

“Copy Quality Not OK” occurs if either the error percentage is to o high or too

many consecutive lines contain errors. A value of 0 implies that error checking

is not present or disabled.
