Save program with internal trigger

Note
Requirement
To be able to execute this command, you first have to configure the identical transport
connection as the trigger and control source.
This command starts the program saving procedure and internally generates a trigger for
image acquisition. The code is saved with the specified number.
Note that if a program has already been saved with this number and no error occurred during
the save procedure, this program is overwritten. If the save procedure is successful, the
optical reader then goes into processing mode with the relevant program number.

Using the "Query status" command, you then check if the
program change has been successful. If, for example, pro-
gram number "5" is selected and the status is queried, the
string "MR05MGST" can be sent.
You check whether the optical reader has successfully stored
the program and is in processing mode based on <status-
byte> and <currentcodeno>.
