What equipment is involved? What does it cost? What (if any) regulations govern its use? Any help appreciated.

How will the modems establish a connection without dialing or even a dialtone? Also what is synchronous mode for modems? I have two US ROBOTICS SPORTSTER 14.4ks. Thanks. [TELECOM Digest Editor's Note: It depends on how the phone line responds. If it is the kind of line where when the phone on one end is taken off hook the phone on the other end rings automatically (this is *not* a one-number speed dial type of thing; it is done in the central office) then the modems will work the same as always. The modem on either end is taken off hook with ATO. Period. That's all you enter. That 'phone' going off hook signals the central office to ring the other end and the distant modem responds in the usual way.

Is there any discussion or literature regarding such claims, or can they all be immediately dismissed as garbage?

Generally speaking, it is a non-issue. It takes a lot more power than a cellphone antenna can radiate before it matters. If John Higdon sees this, he may well decide to respond. He did so the last time this topic arose here. He has worked around RF radiation for years, and lots of it at that. PAT] ------------------------------ From: aa293@detroit.freenet.org (Andrew P.

Maybe I didn't use the right terminology. Does anyone know why they couldn't do this?
