If training with a particular remote
terminal always takes too long, the
initial modem rate may be too high.
Reduce the initial
TX
modem rate
using these bits.
4-5 Not used Do not change these settings.
6 AI short protocol
0: Disabled
1: Enabled 0: AI short protocol is disabled for
transmission

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.

DIS/NSF detection method
Bit 3 Bit 2 Setting
0 0 First DIS or NSF
0 1 Second DIS or NSF
1 0 First DIS or NSF
1 1 Setting disabled (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.
4 V.8 protocol
0: Disabled
1: Enabled If transmissions to a specific
destination always end at a low
modem rate (lower than 14,400 bps),
disable V.8 protocol so that V.34
protocol will not be used.
0: V.34 communication will not be
possible.
5 Compression modes available in
transmit mode
0: MH only
1: All available compression modes This bit determines the capabilities
that are informed to the other
terminal during transmission.
