2.4 Commands 2 – 11
Command Error
LCME?
Query the last command error code. A query of
LCME?
always clears
the error code, so a subsequent
LCME?
will return
0
. Valid codes are:
Value Definition
0 No execution error since last
LCME?
1 Illegal command
2 Undefined command
3 Illegal query
4 Illegal set
5 Missing parameter(s)
6 Extra parameter(s)
7 Null parameter(s)
8 Parameter bu
ff
er overflow
9 Bad floating-point
10 Bad integer
11 Bad integer token
12 Bad token value
13 Bad hex block
14 Unknown token
*IDN
Example:
LCME?
4
The error (4, “Illegal set”) is due to the missing “
?
”.
Parity
PARI(?) { z }
Set (query) parity
{
to
z =
(
NONE 0
,
ODD 1
,
EVEN 2
,
MARK 3
,
SPACE 4
)
}
.
After power-on, modules default to
PARI
NONE
.
PARI EVEN
Example:
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 SIM module that return to-
kens will return the text keyword; otherwise they return the decimal
integer value.
Thus, the only possible responses to the
TOKN?
query are
ON
and
0
.
On reset,
TOKN
is set to
OFF
.
TOKN OFF
