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. -- ------------- Remember: No matter how obnoxious it gets, you CANNOT execute a device!
