Save program with external trigger

Note
Requirement
To execute this command, you must first set the DISA bit.
This command starts the program saving procedure. Note that you will then need to
separately send/set a trigger signal at the earliest after receiving the response string.
The program 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.
