Either he doesn't understand market forces, or he's truly clueless. I have an older Avatex 1200 which does not have a command-escape sequence of any kind. The only time you really *must* have one is if you don't have a DTR pin on your serial port (eg, Macintosh), and you need a way to make the modem hang up. All other uses are optional. Most modems will hang up if you drop DTR, but I ran into one piece of software that doesn't even try that, and insists that you must have some kind of command-escape (although it doesn't have to be Hayes-compatible). The program is Compu$erve's CIM ("Compu$erve Information Manager"), which is a windowed front-end for using Compu$erve. When you log off from CIS, you're still connected to their packet network, so you don't lose carrier, and the modem just sits there waiting for something to happen. When I mentioned this on their CIM support forum, they were, as you say, "truly clueless". They suggested using a batch file that dropped DTR after I exited the program... I can think of a couple of simple alternatives to the Hayes method, but I think it's more likely that the manufacturers will just continue to pay royalties to Hayes, as most of them are doing now. ================== zaphod@madnix.UUCP (Ron Bean) {harvard|rutgers|ucbvax}!uwvax!astroatc!nicmad!madnix!zaphod
