Response 3 of this note states that they implemented ^T to generate
a signal which a user process traps and processes.  I didn't do
it that way.  I simply changed the tty driver.  The other method
however seems very attractive since it allows a user to determine
what should be printed out.  Also, my implementation could not
print out any info from the user space since the ^T was processed
at interrupt time.  The signal method would cure that problem.
Any diffs available?
