COMMENTS
These bits set the acceptable modem carrier
drop time at the non ECM mode.
Try using a longer setting if error code 0-22 is
frequent.
This switch setting determines if high-speed
receiving ends if the carrier signal is lost when
receiving during non-ECM mode
Do not change the settings
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 6 s of CFR.
Do not change the settings.
