Description
This parameter is used to broadcast arbitrary commands to equipment attached to the RS-232 port. If the
ser_control_mode parameter is set to broadcast for the RS-232 port, then the data in the string will be sent
to the RS-232 port. If it is set to command then setting this parameter has no effect.
Special characters may be included in the string by escaping them. Since the string format already uses a
backslash to escape double quote characters, a double backslash must be used to escape the special
characters for this parameter. The following escape sequences are supported.
● \\ -- a single backslash character
● \\n -- new line
● \\r -- carriage return
● \\xNN -- byte value in hexadecimal (must contain exactly two digits)
