Do a communication check for configured TMC drivers. Trinamic drivers that support this feature are TMC2130, TMC2160, TMC2208, TMC2209, TMC2660, TMC5130, and TMC5160.

• With no parameters, this command returns the current settings for all installed and supported Trinamic stepper drivers.
• Send M122 I to re-initialize drivers after a late power-on. Use S[0|1] to enable/disable continuous debugging output.
