Parameter: X 1... 127, ASCII code of the character (decimal).
Defines the BREAKIN character used for PACTOR and AMTOR.

TX (BREAKIN). Because this command is used very often, the PTC accepts the
BREAKIN character only directly in the converse mode, that means that the command
cannot be used after the cmd:-prompt.
The BREAKIN character may be changed to any other convenient character with this
command at any time.
<Ctrl-B> as BREAKIN character is defined with the command: BK 2.
The following characters are not permitted: 8 (Backspace), 13 (CR), 32 (Space), 30
(IDLE), 17 (XON), 19 (XOFF), and other already specified special characters.
