Any comments on the following: 1. I figure that any new modem should implement at least a subset of the cxommands of a Hayes SmartModem. Does anyone want to speculate what subset should be implemented. Do you know of any command(s) that are very useful/useless. 2. Do any of you know of any additional commands that should be implemented on a new modem. Would implementing a superset of the Hayes commands cause any problems with modem software out there. What about storing several numbers, a login sequence etc. 3. Is it worthwhile to implement some form of security on the modem itself to screen incoming calls? Something like a password that has to be entered failing which the connection will be broken. 4. What switches/LEDs on a modem are absolutely necessary and what are of doubtful utility. Also does size really matter. 5. Is it worthwhile/possible for one modem to follow both Bell and CCITT standards? 6. Is it desirable to make a modem both synchronous and asycnchronous. 7. Does anyone know anything about the error-rate found proctically on various 1200 baud chip sets out in the market. I invite all speculation. If you have any special reason to think a certain way please tell me about it. Also if you have any other comments about 1200 baud modem design please tell me about them. Thanks.
