AT^SISX Internet Service Execution
The
command sends ICMP (Internet Control Message Protocol) Echo Requests to a target IP address
or host name (also referred to as Ping command).
The
command can be used any time while a connection profile, i.e. a bearer, is active. The bearer may
have been started either with
, or if a service is in use, with
. If issued although no bearer is
active or no connection profile created at all,
returns ERROR.
The
write command starts the available service type
, i.e. the ping command. The com-
mand returns one row for every ICMP Echo Request (max. 30 lines, see parameter
). The last Ping
response line is followed by an empty line, then another two lines appear to report a statistic calculated from the
Echo Request responses. To stop the periodic ping type any character, e.g. "AT" or "at". After calling the ping
command the AT channel is blocked until all ICMP requests are executed.
Sending the Ping command does not restart the inactivity timeout "inactTO" of the used connection profile (see
), i.e. if the bearer was opened with
the "inactTO" value remains "-1" (= inactivity timeout dis-
abled), and if the bearer was opened with
the "inactTO" value set with
remains applicable.
The Ping command can only be used to prevent that a network initiated inactivity timeout closes the bearer (see
also description of
).
