Hi! I got a Telebit T1000 modem recently. I want to use it on my Mac. But I can't figure a way to do it. Do I need a special cable for it? I have tried the cable connecting Mac with my old 2400 baud Hayes-compatible modem. But every time the T1000 seems to drop back to slow mode after connecting with the other system. Another phenomena was that the DTR light had never turned on. Do I need a comm software which support DTR? Since I am quite naive in modem, any experience/suggestion from you kind souls is grateful. Thanks in advance. Jack C. Hwang

I hard-reset it before connecting it, so I know I haven't got any of the settings out of default. Make sure you are talking to the modem *at* 9600, or force the connection speed and lock the interface speed. (See the manual.) Many Telebits answer with the PEP tones *last*, since modems which can detect "voice" connections are confused by PEP (and, for that matter, by some V.32 modems). In this case, you *must* force the modem to 9600 baud connect, or it will respond to the slow connect tones instead of waiting for the PEP. Don't expect a T1000 to connect to a V.32 modem, or to the proprietary Hayes and USR modems. +--------------- | Another phenomena was that the DTR light had never turned on.

I would suspect that it's the cable that isn't right, anyway; the Mac does not lend itself to direct hacking with the serial ports and it's not necessary (contrast this with PClones, where it's the *only* way to get decent speed from the modem). The standard driver (well, the "RAM driver" if we must be pedantic; I've been nailed by a number of armchair pedants of late --- this matters only on the Mac 128K) automatically supports DTR. ++Brandon -- Me: Brandon S.
