3 AT Commands for FAX

The following commands can be used for FAX transmission. If the ME is acting as a F ax modem to a

PC-based application (e.g. “WinFax“) it is necessary to select the prop er Service Class (Fax Class)

provided by the ME. The ME reports its Service Class capabilities, the current setting and the range of

services available. This is provided by the AT+FCLASS comm and (see pg. 51).

Note: When sending a FAX with a standard FAX application for Pers onal Computers it is recom-

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

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

Note: Be aware that there is a difference between Service Classes 2 and 2.0! Only the first is applica-

ble to the ME.

Responses that may occur during a fax call are presented in the form of Unsolicited Result Code s

(URCs). A summary of Fax specific URCs is listed in Chapter 9.1.4, Table 14.

Read command

AT+FBADLIN?

This command defines the “Copy-Quality-OK”-threshold. If <badline> c onsecu-

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 p ixel 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 too high or too

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

is not present or disabled.
