AT&D2
=Discon
The modem hangs up and enters command mode when an on-to-off DTR transition is detected,
while the modem is in data, test, or escape mode. If DTR is low, the modem does not auto
answer.
AT&D3
=Reset
The modem hangs up (if connected) and loads the specified option set when an on-to-off DTR
transition occurs. If DTR is low, the modem auto answers.
AT&D4
=Tail
This setting is similar to 108.1 except that the modem auto answers an incoming call even if
DTR is off. When DTR transitions from off to on, the modem connects to the telephone line
and dials (if the Default Dial option is enabled).
AT&D5
=108.1
The DTR signal emulates the function of the Talk/Data (
at the Home position) key on the
modem’s front panel. An off-to-on DTR transition instructs the modem to connect to the
telephone line. If the modem detects an incoming ring, it answers the call. If the modem does
not detect an incoming call, the modem dials the number specified by the Default Dial option.
An on-to-off DTR transition disconnects the modem from the telephone line.
AT&D6
=108.2
When the modem is disconnected from the telephone line, and DTR is turned on by the DTE,
the modem responds to all AT commands. When the DTE turns DTR off, the modem does not
respond to dialing and answering AT commands, but responds to all other AT commands. The
DTR signal must remain on throughout the connection. An on-to-off DTR transition
disconnects the modem from the telephone line. If DTE is low, the modem does not auto
answer.
AT&D7
=108.2/Bsy
When the modem is disconnected from the telephone line, and the DTE asserts DTR, the
modem responds to all AT commands. The DTR signal must remain asserted throughout the
connection.
When the DTE de-asserts DTR:
• The modem disconnects from the telephone line. If DTR is de-asserted,
the
modem activates Busyout status.
• The modem does not respond to dialing and answering commands, but responds
to all other commands.
AT&F
