    Can't send from Serial Plotter to Teensy

    At the bottom of the Serial Plotter on Arduino 1.8.13, there is a text entry box and a 'Send' button, as well as a widget to select line endings. In a recent program I added code to plot histogram data on the Serial Plotter. I would like to activate this function by sending a 'g' character to my Teensy program. I never seem to get the character at the Teensy. Is this a known issue? Is it unique to the current version of Arduino and Teensyduino? (I'm working with 1.8.13 and TD 1.53 and using a T4.1.

    I'm burned out for today, but I'll post some sample code in the morning.

    If the plotter works in the same way as the Serial Monitor and you only type the 'g', it won't be sent. You have to hit Enter as well.

    I have this exact same issue. I'm waiting on a character reading from Serial to continue.
    It works in Serial Monitor by sending the relevant char, but it doesn't work in Serial Plotter. Both are set to "Both NL & CR", and I tried various termination settings.
    I hit 'Send', or if I tap 'Enter' it doesn't matter.

    Surely someone would have come across this before. Any ideas?

    Nevermind, answer found here:
