Add buzzer

I've found myself hoping for an audible sound to alert me to operator interactions and the end of test. 

Adding a buzzer would help. I could see that as part of a custom PPC, or even better part of the PLT.

  Hi Nick,

  The PLT-300A does indeed not include any buzzer, but one can definitely be integrated in a custom PPC.
  Without a PPC, one or more buzzer could be hooked up to DDTPxx signals, and controlled from the test plan.

  Another approach would be to connect a USB-CDC adapter to the PLT, hook that up to a terminal emulator, and use an UART interaction command ( https://docs.pltcloud.com/TestPlanReference/uart/ ) to send a BELL control character (0x07) to produce an audible sound in the terminal emulator.    

  We might consider including some sound maker in a future revision of the PLT, but we're mindful that it usually already quite noisy on a production floor.
