These bits set the acceptable modem carrier drop
time.
Try using a longer setting if error code 0-22 is
Value (ms) frequent.

Determines how the machine will respond when it
detects a drop in the carrier signal during non-ECM
communication.
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 setting.
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 setting.
