3.2.4 Command Response Time-Out
Every command issued to the Telit modules returns a result response if response codes are enabled
(default). The time needed to process the given command and return the response varies from
command to command and may depend also from the network on which the command may interact.
As a result every command is provided with a proper time-out period, if this time elapses without any
result from the operation, then an ERROR response can be reported as if the operation was not
successful and the operation is anyway terminated.
The time-out period is quite short for commands that imply only internal set up commands, but may be
very long for command that interact with the network (or even a set of Networks).
The default time-out is 100 ms for all the commands that have no interaction with the network or upper
software layers.
In the table below are listed all the commands whose time-out differs from the default 100 ms and
their effective time-out is reported:
