What is the device's current value for the setting(s).
*
What is the range of possible values for the setting(s). (The device's
response uses a dash (-) to indicate a continuous range of values. A
pipe (|) separates items in a list of non-continuous values.)
Tag Field Usage
When a query is used in place of a Tag field, the query applies to the
entire set of commands available for the particular storage table indicated
by the Storage field of the command. In this case, the SubTag and Data
fields should not be used because they are ignored by the device.
SubTag Field Usage
When a query is used in place of a SubTag field, the query applies only to the
subset of commands available that match the Tag field. In this case, the Data
field should not be used because it is ignored by the device.
Data Field Usage
When a query is used in place of the Data field, the query applies only to
the specific command identified by the Tag and SubTag fields.
Concatenation of Multiple Commands
Multiple commands can be issued within one Prefix/Storage sequence.
Only the Tag, SubTag, and Data fields must be repeated for each com-
mand in the sequence. If additional commands are to be applied to the
same Tag, then the new command sequence is separated with a comma
(,) and only the SubTag and Data fields of the additional command are
issued. If the additional command requires a different Tag field, the
command is separated from previous commands by a semicolon (;).
Responses
The device responds to serial commands with one of three responses:
ACK Indicates a good command which has been processed.
ENQ Indicates an invalid Tag or SubTag command.
NAK Indicates the command was good, but the Data field entry was out
of the allowable range for this Tag and SubTag combination, e.g.,
an entry for a minimum message length of 100 when the field will
only accept 2 characters.
When responding, the device echoes back the command sequence with the
status character inserted directly before each of the punctuation marks (the
period, exclamation point, comma, or semicolon) in the command.
Examples of Query Commands
In the following examples, a bracketed notation [ ] depicts a non-displayable
response.
