This is incorrect; the setting which causes the modem to reset itself ALSO hangs up. There is no way to reset the modem without hanging up (it's not clear that that makes much sense, anyway). > 3) The DTR light on the front panel is always on, regardless > of the actual state of DTR, even when the modem is configured > to use DTR to prevent answer/hang up the phone. False. The light tracks the state of the DTR line UNLESS you configure the modem to ignore DTR entirely, in which case the light remains on. I have had no problems with my Hayes 2400 that are the result of poor functional design. It did fail to survive a lightning strike on the phone pole across the street... -- tom lane Internet: tgl@zog.cs.cmu.edu UUCP:!zog.cs.cmu.edu!tgl BITNET: tgl%zog.cs.cmu.edu@cmuccvma
