• Print a line to the serial port with (carriage) return and newline (\r\n), also called (CR LF) at the end of it.

    ...kind of what the doc should read.

    Now CR info with a hilarious and other (interesting) notes...

    PS: I guess that todays old type writers are now such a thing of the past barely remembered where this notation came from... and the linux behavior for (\n) or (LF) as line end and begin of a new line is not helping much either... nor the chain / band printers from a while ago...

    In attached clip, a lever is used to return the spring loaded carriage to its type begin position. It is a lever and not just a handle, because it is hinged onto the carriage, and on pushing, it first turns the rubber print drum by the set amount of 1..1-1/2..2 lines (nicely seen in 3rd clip). The demonstrator in this video uses the Tab key - most type writers had one to the left and one to the right - to move the carriage from one tab to the next. This were of course all left tabs, settable at any position. So are the left and right margins.

    The ringing bell alarms the typer that there are 8..6 characters space left to the set right border and LF CR or hyphenation and LF CR is to think about...

    First clip

    means: Type writer LF CR.

    second clip

    means: CR because C not paid (or parking not paid or illegally parked... ;)>

    Third clip: LF CR (start 30 seconds into the clip)

    . - PS: sorry ladies for this gender stereotype clip... (although fits/suites/serves the current alternative-facts gov / culture very much... ouch :(((
