Error messages
Error messages are delivered via the serial interface according to circumstances.
These messages consist of a letter and an error number which identifies the type of
error. In data formats 28 and 64 the valid error messages are in brackets.
Example:
By the interface is sent the command “X”. This command is not defined and the mes-
sage “M2 <CR> <LF>” is returned.
