If the keep alive mode is not equal to zero, then the keep alive function will trigger. The function
allows a persistent physical connection to be established. If enabled and a remote host is not
reached, the physical connection is disconnected (if connected) and reestablished.
Set Value: AT#KEEPALIVEMODE=<Keepalivemode value>
View Values: AT#KEEPALIVEMODE? or AT#VKEEPALIVE or AT#VALL
0 Keep alive mode is disabled
1 Keep alive mode is enabled using a TCP connection
2 Keep alive mode is enabled using ICMP
0
AT#KEEPALIVEMODE=1
If the keep alive session is TCP, then keep alive port controls the remote host port number.
Set Value: AT#KEEPALIVEPORT=<Port Number value>
View Values: AT#KEEPALIVEPORT? or AT#VKEEPALIVE or AT#VALL
Set the port number that the Profile will use:
From 1 to 5 numeric digits (0 to 9).
Note:
Numbers above 65535 are illegal since port identification fields are 16-bits long in the IDP
header.
0
AT#KEEPALIVEPORT=xxxxx
The remote address for both TCP and ICMP keep alive.
Set Value: AT#UDPSERV="<Keepalive Server Addressvalue>"
View Value: AT#KEEPALIVESERV? or AT#VKEEPALIVE or AT#VALL
Set the Remote Server Address value that the Profile will use:
32-bit number is dotted-decimal notation (i.e., xxx.xxx.xxx.xxx) or
Alphanumeric ASCII text string up to 120 characters if DNS is working.
None
AT#KEEPALIVESERV="xxx.xxx.xxx.xxx" or AT#KEEPALIVESERV="some.address.com"
This parameter determines the delay before the keep alive mechanism will check the remote host
for connectivity.
Set Value: AT#KEEPALIVEDELAY=<Data Delay value>
View Value: AT#KEEPALIVEDELAY? or AT#VKEEPALIVE or AT#VALL
Set the delay value in minutes
Integer between 0 and 65535
100
AT#KEEPALIVEDELAY=xxxxx
