Command
RESET
ASM is reset. The active command is terminated.
(If an MDS command was terminated with RESET, the reset acknowledgment
reports error 1F.)
The RESET command can be used to switch the ASM to various operating modes.
Write
Write data block to MDS
Read
Read data block from MDS
This command is required when a new (not yet write-accessed) MDS is being used
or after failure/replacement of the battery or when MDS is to be run in ECC mode.
The MDS is already initialized for normal use.

SLG status
Returns as result the status byte, the selected write/read device and the
ANZ_MDS_present_ bit. This command checks to determine whether a write/read
device is connected to the ASM and, if so, whether it is okay and ready for
operation. An appropriate error is reported, if necessary. With MOBY U various
diagnostic data can be fetched from the write/read device.
NEXT
The following command(s) refer(s) to the next MDS. The user can immediately start
a command even though the old MDS is still in the field. The NEXT command must
only be programmed when MDS_control_ = 2 was set in the RESET command.
A NEXT command must arrive between 2 MDS passes or an error message will
occur. Conclusion of an MDS pass with a NEXT command is also valid after the
MDS has already left the field or the next MDS is already in the field.
END
Terminate communication with MDS
