CÓPIA NÃO CONTROLADA
If this bit is set to 0, ECM is switched off for all
communications.
In addition, V.8 protocol and JBIG compression
are switched off automatically.
Do not change the settings.
(0,1) - The machine will disconnect the line
without sending a fax message, if the last 8 digits
of the received CSI do not match the last 8 digits
of the dialed telephone number. This does not
work when manually dialed.
(1,0) - The same as above, except that only the
last 4 digits are compared.
(1,1) - The machine will disconnect the line
without sending a fax message, if the other end
does not identify itself with an RTI or CSI.
(0,0) - Nothing is checked; transmission will
always go ahead.
NOTE: This function does not work when
dialing is done from the external
telephone.
Do not change the setting.
The setting determined by these bits is informed
to the transmitting terminal in the pre-message
protocol exchange (in the DIS/NSF frames).
