Thanks to everyone who's responded so far. I think I incorrectly phrased the question, so I'll ask it again. I'm using a V92 modem. How do I "slow it down" so as to be able to call a TTY/TDD user? I've been through the manual, and can't find instrcutions on this. Is there softwware to do this, or can I do it manually? Paul W5PDA/4
