These bits set the acceptable modem carrier drop time.
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 5 s of CFR.
Do not change the settings.
