(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.
