Return:
Indicated actions performed a. non-control characters are displayed (opcodes DEh and DFh control whether the attributes are left or changed to the current attrib) b. CR/LF/BS/Tab cause the usual cursor movement c. ESC starts a data structure with additional commands if following byte is less than 20h; otherwise, it is written to the window.STACK:
