Commands in basic read/write operating mode
The commands can be divided into read/write commands and system commands.
The read/write commands allow access to the data storage area to which the user has
access. The syntax for these commands depends on the type of data carrier selected.
All steps can only be implemented with read/write heads.
All control instructions to the system are defined as system commands.
These commands are introduced by one character, the command header, which may
be followed by various parameters. All ASCII values for these characters are added
in a check sum. The check sum comprises one byte only. Any carry-over is truncated.
After the check sum, an ETX character (End of Text) is transmitted, indicating the end
of the command.
