/BREAK=break-character
    Selects the break character. The break character is used to
    generate a break on lines that expect a break rather than a
    carriage return. To generate a break, press Ctrl/break-character.
    The break character can be any ASCII character between @ and z.
    You cannot select a character currently defined as either the
    command character (see the description of the /COMMAND=command-
    character qualifier) or the disconnect character (see the
    description of the /DISCONNECT=disconnect-character qualifier).
    The ASCII characters between @ and z include the alphabetic
    characters in both upper and lower cases, the "at" sign (@),
    the backslash (\),  the right bracket (]), the circumflex (^),
    the underscore (_),  and the grave accent (`).
    By default, the break character is the right bracket (]).
