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.
