COMMENTS
The machine uses inch-based resolutions for
scanning. If "inch only" is selected, the printed
copy may be slightly distorted at the other end if
that machine uses mm-based resolutions.
If the setting is "Disabled", the bit switch setting is
used.
(0, 1): Use this setting if echoes on the line are
interfering with the set-up protocol at the start of
transmission. The machine will then wait for the
second DIS or NSF before sending DCS or NSS.
If the setting is "Disabled", the bit switch setting is
used.
If transmissions to a specific destination always
end at a lower modem rate (14,400 bps or lower),
disable V.8 protocol so as not to use V.34 protocol.
0: V.34 communication will not be possible.
If the setting is "Disabled", the bit switch setting is
used.
This bit determines the capabilities that are
informed to the other terminal during transmission.
If the setting is "Disabled", the bit switch setting is
used.
