The antenna attempts to write a fixed code once.
"MDT../28-L ": <FixLen> = 5
<FixType> = '02' ASCII (30h 32h), the fixed code cannot be changed
'15' ASCII (31h 35h), the fixed code cannot be overwritten
Write fixed code MDT../28-L
A fixed code can be entered in the data carrier MDT../28-L, which must comprise
5 bytes. The command "SX" is used for this.
This fixed code can then be read with the commands "SF" and "EF". If an MDT../28-L
is written with data with the command "SW", a subsequent fixed code read attempt
can return incorrect data or an error status.
If the fixed code was written so that it cannot be changed, a subsequent "Write
Fixcode" command results in an error.
Exception: The fixed code to be written is identical to the value already in the MDT.
