2.2 Command Response Timeout<br />
Every command issued to the Telit <strong>GE863</strong>-<strong>QUAD</strong> / <strong>PY</strong> returns a result response if response codes are<br />
enabled (default) (see command ATQn). The time needed to process the given command and return<br />
the response varies from command to command and may depend also from the network on which the<br />
command may interact. As a result every command is provided with a proper timeout time, if this time<br />
elapses without any result from the operation, then the ERROR response is reported as if the<br />
operation was not successful.<br />
The timeout time is quite short for commands that imply only internal set up commands, but may be<br />
very long for command that interact with the network (or even Networks).<br />
NOTE: In case no response is received after the timeout time has been elapsed, then try<br />
repeating the last command and if still no response is received until the timeout time, then an<br />
Unconditional Shutdown MUST be issued and then the device shall be powered ON again.<br />
In the table below are listed all the commands whose timeout differs from the default 100 ms and their<br />
effective timeout is reported:<br />
