-"""
-This tool uses pexpect to test expected Canonical mode length.
-
-All systems use the value of MAX_CANON which can be found using
-fpathconf(3) value PC_MAX_CANON -- with the exception of Linux
-and FreeBSD.
-
-Linux, though defining a value of 255, actually honors the value
-of 4096 from linux kernel include file tty.h definition
-N_TTY_BUF_SIZE.
-
-Linux also does not honor IMAXBEL. termios(3) states, "Linux does not
-implement this bit, and acts as if it is always set." Although these
-tests ensure it is enabled, this is a non-op for Linux.
-
-FreeBSD supports neither, and instead uses a fraction (1/5) of the tty
-speed which is always 9600.  Therefor, the maximum limited input line
-length is 9600 / 5 = 1920.
-
-These tests only ensure the correctness of the behavior described by
-the sendline() docstring -- the values listed there, and above should
-be equal to the output of the given OS described, but no promises!
