- Action type commands. This type of command may be “executed” or “tested”.
•
“executed“ to invoke a particular function of the equipment, which generally involves more
than the simple storage of a value for later use
•
“tested” to determine:
(if the command #SELINT=0 or #SELINT=1 has been issued)
if subparameters are associated with the action, the ranges of subparameters values that
are supported; if the command has no subparameters, issuing the correspondent Test
command (trailing =?) raises the result code “ERROR”.
NOTE: issuing the Read command (trailing ?) causes the command to be executed.
(if the command #SELINT=2 has been issued)
whether or not the equipment implements the Action Command (in this case issuing the
correspondent Test command - trailing =? - returns the OK result code), and, if
subparameters are associated with the action, the ranges of subparameters values that
are supported.
Action commands don’t store the values of any of their possible subparameters.
Moreover:
•
(for #SELINT=0 or #SELINT=1 only)
An enhanced test command (trailing =??) has been introduced to maintain backward
compatibility for those commands whose subparameters changed the range of possible
values from version to version.
•
(for #SELINT=2 only)
The response to the Test Command (trailing =?) may be changed in the future by Telit to
allow the description of new values/functionalities
•
(for #SELINT=2 only)
If all the subparameters of a parameter type command +CMD (or #CMD or $CMD) are
optional, issuing AT+CMD=<CR> (or AT#CMD=<CR> or AT$CMD=<CR>) causes the OK
result code to be returned and the previous values of the omitted subparameters to be
retained.
