When it is set to ON, the printer transmits an "XOFF" for busy and sends an
"XON" for not busy. When it is set to OFF, the printer signifies the busy status
over hardware signals that can be detected by the host as "DSR" or "CTS".
When parallel interface is used, both switch positions 3 and 4 should be set to
OFF.
For switch position 8, when it is set to ON, the printer responds to a carriage

However it works for some old editors that express the change to a new line
with only either one of the LF code or the CR code.
