frequent.

4 Maximum allowable frame
interval during image data
reception.
0: 5 s 1: 13 s
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.

6 Reconstruction time for the
first line in receive mode
0: 6 s 1: 12 s
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.
7 Not used Do not change the setting.
