Hi Daniel, I don't remember seeing a Hayes command for that, at least not a standard one. You can accomplish this though by using a device from Radio Shack. I can't remember exactly what they call them, maybe a privacy switch. Basically, it prevents you from picking up while the line is in use. You won't get a "phone is off hook" message from the modem but you should be able to make it tell you that it couldn't get dialtone. In that case, you'll be pretty sure that the line was in use elsewhere and you just have to try again in a few minutes.
