0: This uses the fixed table in the ROM for dial tone detection.
1: This uses the specific parameter adjusted with SRAM (69ECBEH -
69ECDEH). Select this if the dial tone cannot be detected when the "Normal
parameter: 0" is selected.

Comments
These bits set the acceptable modem carrier drop time.
Try 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.
