Here's an AT&T Modem FAQ, for those interested. I got it from Usenet's comp.dcom.modems. If you're considering a DataPort, this is a must-read. It's nearly an ad, but still very helpful. It appears to be written by some tech-support type person from AT&T Paradyne. I've left his name and email address in the message only because he asks those with more questions to email him. This is the first edition FAQ dated 10/22/93. Widen your window to make it more easy to read.
