This bit set the maximum interval
between EOL (end-of-line) signals and
the maximum interval between ECM
frames from the other end.
Try using a longer setting if error code
0-21 is frequent.
Do not change the settings.
When the sending terminal is controlled
by a computer, there may be a delay in
receiving page data after the local
machine accepts set-up data and sends
CFR. This is outside the T.30
recommendation. But, if this delay
occurs, set this bit to 1 to give the
sending machine more time to send data.
Refer to error code 0-20.
ITU-T T.30 recommendation: The first line
should come within 5 s of CFR.
Do not change the settings.
