Genicom GEK 00031B manual Decawm, Decpsm, Deccrnlm, Vfu

DECAWM		Autowrap Mode: Determines what happens when text exceeds the
		right margin. When autowrap is enabled and text exceeds the right
		margin, the active print position moves to the left margin on the next
		line. When autowrap is disabled and text exceeds the right margin,
		data will be lost.
DECPSM		Pitch Select Mode: Controls the Set Horizontal Pitch (DECSHORP)
		sequence. When Pitch Select Mode is enabled, the current font
		determines the pitch. When disabled, the printer uses the horizontal
		pitch selected by the DECSHORP sequence.
DECCRNLM		Carriage Return / New Line Mode: Defines the response to the
		Carriage Return character. When Carriage Return New Line Mode is
		enabled, a received Carriage Return will return the active position to
		the left margin on the next line. When disabled, a Carriage Return will
		return the active position to the left margin on the current line.
VFU		Load Vertical Format Unit: This sequence will download the VFU
		from the host. All data following this load sequence is placed into the
		VFU memory until terminated with the End Load sequence. Any
		command entered during the load is ignored except the End Load
		sequence. All data must be in the VFU load format. If an error is
		detected during the load, the load is aborted. If a load exceeds the
		form length, the load is aborted. Cancelled loads default to the
		current form length setting.
