Selectors 5 and 6:
l
These selectors determine whether or not the equipment automatically disconnects a line upon
detection of a busy tone in automatic sending mode.
Setting selector 6 to "0" ignores a busy tone so that the equipment does not disconnect the line.
Setting selectors 5 and 6 to "0" and "1," respectively, makes the equipment detect a busy tone
only after dialing and disconnect the line.
Setting both of selectors 5 and 6 to "1" makes the equipment detect a busy tone before and after
dialing and then disconnect the line.
