Extended AT% Command Set (Command Defaults in Bold)
Command
Action
%$
Display AT% command settings.
%B
Report blacklist. See also S42 register.
%Cn
Data compression
%C0
Disable V.42bis and MNP5 data compression
%C1
Enable V.42bis in transmit and receive paths. If MNP is selected (\N2), then %C1 enables
MNP5 in transmit and receive paths.
%C2
Enable V.42bis in transmit path only.
%C3
Enable V.42bis in receive path only.
%On
Answer mode
%O1
Modem will auto-answer a call in answer mode.
%O2
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.
%Vn
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.
%V0
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
Action
0 <= LVCS <= NOLN
Report "NO LINE" and remain on-hook.
NOLN <= LVCS <= LIUS
Report "LINE IN USE" and remain on-hook.
LIUS <= LCVS
Go off-hook and establish a modem connection.
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.
&V1
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
Action
0 <- LVCS <= (0.0625 x NLIU)
Report "NO LINE" and remain on-hook.
(0.0625 x NLIU) < LVCS <= (0.85 x NLIU)
Report "LINE IN USE" and remain on-hook.
&V2
(0.85 x NLIU) < LCVS
Go off-hook and establish a moden connection.
