From: Bruce L. Conroy <BLC@jpl-vax> I have been using the U.S. Robotics Password ($380 from the Bottom Line) for about 2 weeks. 1) Although I don't know how smart the Hayes unit is, the Password has a number of options, all programmed by sending ASCII strings to the modem. a) Number of times to let the phone ring before answering. b) Tone or pulse dialing. c) Time to wait after dialing for carrier. d) Time to leave the monitoring spekaker on (default is from time dial command is given until carrier is established.) e) force answer mode (can also be set with DIP switch.) f) Local echo (also known as half duplex.) 2) There are several other options, which don't seem very important. 3) Once carrier is established, the onlyhing the modem will respond to is a one second pause followed by +++ followed by another one second pause. Four pluses are ignored. (the + character can also be programmed to any other character.) 4) The unit seems to run hot. Only time will tell if this is a problem or not.

From: Mike Ciaraldi <ciaraldi@Rochester.ARPA> One other problem has shown up on my Password modem, which might also be on the S-100 version (I'd like to find out). If you have the modem powered up and attached to the phone line, and someone calls you and you answer it manually on the first ring (i.e. before the modem would have picked it up) you will hear the modem come on anyway. You are trying to talk to the person who called you, and the modem is busy going "ooooooooooooo" at you both. It happens in the other direction, too. If you dial someone with your phone, when they answer the modem picks up and goes "oooooooo". Anyone know how to avoid this (other than unplugging the modem from the phone line or turning it off)?
