I have two processors, a Feather & a Teensy. I've been able to get both working Master/Slave to the serial monitor. The teensy just puts what I type from the serial monitor -> its screen. I can send commands to the Feather with the serial monitor and it responds as it should. I tied TX of the teens…

Serial port <-> question.

Once it sees the PC, does it turn off the pins?
