I have a system at home which cannot generate a "break" signal.  I have
asked various random people more knowledgeable in electronics than I about
what exactly a "break" is.  I was told: (1) the DTR (data terminal ready) line going
to ground for 300+/- 200 msec; (2) the XMT (Transmit Data) line going to ground for 500msec.
I wired up a small switch on both the TD line and DTR line, but neither
generated a "break" at the test systems (a Univac and a Unix).  So,
I'm appealing to the net: is there some cheep minor hardware trick
that will allow me to generate a "break" signal?  This is vital since
the systems I usually use *absolutely* require a "break".  I only
have one part of my home system which can generate a "break"--an atari 800 with
the TELELINK program in ROM. 

Any and all replies will be welcome and if there is any interest
I'm summarize to the net.

Thanks,
