Selectors 1 through 6:
These selectors are intended for the manufacturer who tests the equipment for the Standard.
Never access them.
Selector 7: Resolution definition
This selector determines whether the equipment issues a standard or non-standard (fine/su-
perfine) resolution statement when the empty space of the memory shared by the receive
buffer and recording buffer becomes insufficient to receive data at high resolution.
If this selector is set to "0," the equipment issues a standard resolution statement which in-
forms the calling station that the station called can receive data only at the standard resolu-
tion.
If it is set to "1," the FAX3550/8000P/MFC4450/4550/4550plus/6550MC issues a fine resolu-
tion statement and the FAX3650/8200P/MFC7550MC/7650MC/9000/9500 issues a superfine
resolution statement. (NOTE: The FAX3550/8000P/MFC4550/4550plus/6550MC having an
optional memory issues a superfine resolution statement.)
