Are there any customary tricks to making a diagnostic serial port

I am not aware of any standards.

Some devices will respond to a few CR-LF, as in pressing the enter key
a few times, but those are probably mostly intended to be accessible
by the user.

A device like this may very well have the serial port disabled in
firmware.
