	You might try "stty susp u".

	At least on berkeley unix, stty understands u means undefine
this command, so the terminal susp feature will not be possible to
generate from the terminal. (until you define it again with stty, or
an ioctl directly defines it)

WAIT!!!  AN ENTIRELY RANDOM THOUGHT: READ THE MANUAL ON A SYSV
BOX!!!!!!

SYNOPSIS
     stty [ -a ] [ -g ] [ options ]

DESCRIPTION
     stty sets certain terminal I/O options for the device that
     is the current standard input; without arguments, it reports
     the settings of certain options.

     In this report, if a character is preceded by a caret (^),
     then the value of that option is the corresponding CTRL
     character (e.g., "^h" is CTRL-h ; in this case, recall
     that CTRL-h is the same as the "back-space" key.)  The
     sequence "^'" means that an option has a null value.  For
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^     
     example, normally stty -a will report that the value of
     swtch is "^'"; however, if shl (1) or layers (1) has been
     invoked, stty -a will have the value "^z".


WAIT!!! ANOTHER ENTIRELY RANDOM THOUGHT!!!! TEST IT BEFORE
POSTING!!!!!

	Well, stty susp ^' sets susp to ^g.  Seems that either the
manual or the program is lying to me.

WAIT!!! A THIRD ENTIRELY RANDOM THOUGHT!!!! DON'T BELIEVE THE
DOCUMENTATION, READ THE SOURCE!!!!!

	Perusing the source reveals that "stty susp ^-" sets
susp to undefined.
	
	Caveat: I have never seen UNIX SCO V / 386, so can not say if
its documentation or implemetation tracks what MY sysV R3 box
says/does.  However, both MIPS 3.10 and ARDENT manuals claim that ^'
should be undefine, but implement ^- as the undefine token to
/bin/stty.
