Remote Operation
Device Error
LDDE?
Query the Last Device-Dependent Error code. A query of
LDDE?
always clears the error code, so a subsequent
LDDE?
will return
0
.
Valid codes are:
Value
Definition
0
No execution error since last
LEXE?
1
Reference clock conflict
2
Unable to autocalibrate
ACAL
Example:
LDDE?
0
indicates a successful autocalibration.
Token Mode
TOKN(?)
{
z
}
Set (query) the token query mode
{
to
z
=
(
OFF 0
,
ON 1
)
}
.
If
TOKN
ON
is set, then queries to the SIM918 that return tokens will
return a text keyword; otherwise they return a decimal integer value.
Thus, the only possible responses to the
TOKN?
query are
ON
and
0
.
TOKN OFF
Example:
Response Termination
TERM(?)
{
z
}
Set (query) the
h
term
i
sequence
{
to
z
=
(
NONE 0
,
CR 1
,
LF 2
,
CRLF 3
,
or
LFCR 4
)
}
.
The
h
term
i
sequence is appended to all query responses sent by
the module, and is constructed of ASCII character(s) 13 (carriage
return) and 10 (line feed). The token mnemonic gives the sequence
of characters.
A reset does not alter
TERM
. The value in boldface above is the
power-on value.
TOKN ON; TERM?
Example:
CRLF
3.4.9
Serial communication commands
Note that the SIM918 can only support a single baud rate of 9600,
and does not support flow control. A reset does not change the serial
interface settings; use Device Clear.
