Modem will auto-answer a call in originate mode.
Automatic Line Status Detection
After the %V1 and %V2 commands are issued, the modem will automatically check the telephone
connection for weather or not a line is present. If a line is present, the modem will automatically
check if the line is already in use.
Finally, the modem will check line status both before going off-hook and again before dialing. %V1
uses the fixed method, and %V2 uses the adaptive method. %V0 (default) disables this feature.
Disable automatic line-in-use detection.
Automatic Line Status Detection - Fixed Method.
Description: Before going off-hook with the ATD, ATO or ATA commands the modem compares
the line voltage via LVCS to registers NOLN (U83) and LIUS (U84):
Loop Voltage
0 <= LVCS <= NOLN
NOLN <= LVCS <= LIUS
LIUS <= LCVS
One the call has begun, the off-hook intrusion algorithm operates normally.
In addition, the modem will report "NO LINE" if the telephone line is completely disconnected.
If the HOI bit (U77, bit11) is set, "LINE IN USE" is reported upon intrusion.
Automatic Line Status Detection - Adaptive Method.
Description: Before going off-hook with the ATD, ATO or ATA commands, the modem compares
the line voltage (via LVCS to the NLIU (U85) register:
Loop Voltage
0 <- LVCS <= (0.0625 x NLIU)
(0.0625 x NLIU) < LVCS <= (0.85 x NLIU)
(0.85 x NLIU) < LCVS
