Set Connection Watchdog
Note: This command is only available on MP 750 GPS modems with firmware
version R2_2_1ap or later and on MP 775 GPS modems with firmware version
R3_0_5ap or later.
The Connection Watchdog monitors connections to determine whether the
modem is receiving any data. If the modem is not receiving data, the
Connection Watchdog either sends a DNS query to the DNS server or pings a
specified IP address, depending on how the feature is configured. If data
transmission is resumed following the DNS query or ping, the modem maintains
the connection. Otherwise the modem terminates the connection. If the modem
is in “always-on” mode, the modem attempts reconnection once the connection
is terminated. (See
!MPOPMODE
on page 52.) This command also allows you
to set the modem to either disconnect the data connection or reset the radio
component whenever the Connection Watchdog has detected an invalid data
connection.
