Use the service modem-callback
modems.
Use the
undo service modem-callback
function of modems.
By default, the callback function of modems is disabled.
When a modem line is active, that is, when the modem detects the carrier or data
is being received, you may enable callback. As the service modem-callback
command uses modem scripts to implement callback before entering PPP, it
enables callback before accounting is started. This can thus help you save cost.
# Enable the callback function.
