This is not true!!  From what I have seen, MOST Hayes-compatible modems
aren't!  Oh, they will accept most Hayes 'AT' commands, but they don't have
non-volatile memory, and thus won't accept the '&' commands, nor will they
reset upon DTR drop.

This is why I posted the original article - the modems I have access to don't
have non-volatile memory, nor do they reset upon DTR drop.  They are the [old
version] MultiTech 224AH and a USR Courier 2400 [also old].  I do not know
whether the newer versions of those modems have the needed features or not.

I appreciate all the answers [via email] that I got, but they all basically
said the same thing - use the &D3 command.

I would if I could, but I can't, so I won't!

So, to reiterate the major question [and to restate it a bit]:

	What "Hayes compatible" modems have non-volatile memory
	and will (if desired) reset to the conditions stored in
	that non-volatile memory upon DTR drop?

Thanks again.
