the call without waiting for the PPP server. This is too fast for the PPP server.
13. Hang-up the connection.
The PPP server will attempt to hang-up the modem when either a connection
is closed by a remote peer, or if the modem initialization failed during
the IPC@CHIP boot process.
`. Switch the modem into the command mode (CMDMODE and HANGUPDELAY)
Example:
CMDMODE=+++
HANGUPDELAY=2
These are the default values.
a. Define modem commands and expected answers for hang-up.
Again, up to three sets of these parameters can be given here.
Example:
HANGUPCMD0=ATH0
HANGUPANSWER0=OK
HANGUPTIMEOUT0=2
HANGUPRETRIES0=1
If you enter the string NULL at an HANGUPANSWERx (e.g. HANGUPANSWER0=NULL),
the IPC@CHIP PPP
server will not wait for an answer from the modem.
14. Control the online state while PPP session is open.
You can define three sets of modem control parameters. These parameters are
used to check the online state of the modem at an open PPP connection.
`. Enable online control sequence MODEMCTRL=1.
The default is 0 (disabled).
Example:
MODEMCTRL=1
Also you have to configure a control time interval (in seconds). After each time interval
during which the PPP server receive no data, the server executes the configured modem
commands. The server closes the connection, if one of the expected answers timed out.
a. Define a CTRLTIME.
E.g. CTRLTIME=120 default is 60 seconds
Each of the three parameter sets consists of the following four parameters:
■ CTRLCMD string - Command sent to the modem to initialize it.
■ CTRLANSWER string - Expected modem response to control command.
■ CTRLTIMEOUT integer - Number of seconds to wait on answer from modem.
■ CTRLRETRIES integer - Number of times to repeat modem control sequence if a
previous attempt fails.
Example and default settings:
CTRLCMD0=+++
CTRLANSWER0=OK
