10.10 AT^SICC Internet Connection Close

The AT^SICC write command releases a connection opened with AT^SICO and restores the
Description:
previously set inactivity timeout "inactTO" of the selected connection profile.
The command returns an error if any services are bound to this profile. Before using the AT^SICC
write command be sure that all services were closed with AT^SISC.

Note
Be sure not to mix up the start and close commands connection profiles and service profiles. It is allowed to use only
the combinations AT^SICO / AT^SICC or AT^SISO / AT^SISC.

10.11 AT^SISX Internet Service Execution

The AT^SISX command sends ICMP (Internet Control Message Protocol) Echo Requests to a
Description:
target IP address or host name (also referred to as Ping command).
The AT^SISX command can be used any time while a connection profile, i.e. a bearer, is active.
The bearer may have been started either with AT^SICO, or if a service is in use, with AT^SISO. If
issued although no bearer is active or no connection profile created at all, AT^SISX returns
ERROR.
The AT^SISX write command starts the available service type <service>, i.e. the ping command.
The command returns one row for every ICMP Echo Request (max. 30 lines, see parameter
<request>). 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 AT^SICS), i.e. if the bearer was opened with AT^SICO the "inactTO" value remains "-1"
(= inactivity timeout disabled), and if the bearer was opened with AT^SISO the "inactTO" value set
with AT^SICS remains applicable. The Ping command can only be used to prevent that a network
initiated inactivity timeout closes the bearer (see also description of AT^SICO).
