Error recovery/output
The normal action at any error is to stop in a waiting loop to recover the
error feature. At this "Error Waiting Loop" only command
can be performed and executed.
The error recovery, often performed by pressing the FEED key, releases
the error and sends recovery information on the serial line (RS-232 or
USB), normally <XON>.
