(continued)
Set Connection Watchdog (continued)
When a new connection is established, the modem verifies that the DNS server
is valid or that pings are possible (depending on the <mode> setting), before the
modem begins monitoring for data receipt. If the modem is unable to verify the
DNS server or the ping fails, the Connection Watchdog remains inactive, but the
modem continues to either ping or verify the DNS server at the interval set by
the <dnstime> parameter.
The parameters are:
<rxtime> Interval (in minutes) at which the modem checks whether data
is being received. When this interval is reached, depending on
the <mode> setting, the modem either sends a DNS query or
pings the address specified by the <PING IP> parameter. The
allowed values are 0 to 240. When set to 0, the Connection
Watchdog is disabled. (0 is the default.)
<dnstime> Interval (in minutes) at which the modem checks for a DNS
server or attempts a ping when a new connection is
established. On MP 750 GPS modems with firmware version
2_1_11ap, and MP 775 GPS modems with firmware version
3_0_5ap, the allowed values are 0 to 240. On MP 750 GPS
modems with firmware version 2_1_12ap or higher ,and
MP 775 GPS modems with firmware version 3_0_7ap or
higher, the allowed values are 1 to 240. (30 is the default.)
dnsport# DNS port number used by the MP. The allowed values are 1 to
65535. The default is 7367. To avoid selecting a port number
that is in use by another component, it is advisable to use the
default port number.
dnsname Website name for DNS to resolve (such as
“www.sierrawireless.com”). (The maximum string length is 128
characters.)
AC Reset Flag Flag that determines whether the radio component is
reset when the Connection Watchdog determines that a
connection has failed. When set to 0 (the default), the
Connection Watchdog terminates invalid connections but does
NOT perform a reset. When set to 1, the Connection
Watchdog resets the radio component after terminating the
connection.
Note: In firmware version 2_1_12ap on the MP 750 GPS, and firmware version
3_0_7ap on the MP 775 GPS, the <AC Reset Flag> parameter has replaced
the <max number of CW-triggered disconnects> parameter that was in
firmware versions 2_1_11ap and 3_0_5ap respectively. The <max number of
CW-triggered disconnects> set the modem to reset the radio component after
a specified number of consecutive Connection Watchdog-triggered discon-
nects. (The allowed values were 1 to 65535.)
