10.6 AT^SISC Internet Service Close
Description: The AT^SISC write command closes the TCP/IP connection to the remote peer which was
opened with AT^SISO. All resources are released, all status information parameters, e.g.
<srvState>, <unackData>, <ackData>, <rxCount> and <txCount> counters, are reset. Only the
initial configuration settings are preserved. The service can be restarted any time, using the
same configuration or a new one.

Notes:
• Usage of the PIN is dependent on conditions specified for the command. Not all command types are PIN
protected (for example a write command can be PIN protected while the read command is not). Note: The
table provided in Section 19.3, Available AT Commands and Dependency on SIM PIN uses the same symbols.
• This command is not supported in airplane mode.
