Query range shows
+A8E: (1),(1),(0),(0-2),( ),( )
The 0 in the <v8cf> parameter is the maximum number of octets
allowed for this parameter. The ( ) in the <cfrange> and
<protrange> parameters indicate that the parameter is not
supported.
<signal>: (no default value)
0=none

2=detect both
<msg_en>:
0=disable message detection
