4. Clears any existing error conditions and removes the error message display (if present)
from the bottom of the screen.
5. Disables Display Functions mode (if enabled).
6. Halts any datacomm transfers currently in progress, clears the datacomm buffers.
7. Resets the integral printer, if present.
8. Cancels any pending status requests.
The data on the screen, all terminal operating modes (except Display Functions mode), and
all active configuration parameters are unchanged.
