A friend of mine loaned me a DEC DF03 modem that he got 3rd or 4th hand,
without documentation of any kind. I am trying to connect it to an AT&T
Unix PC, and would appreciate it if someone out there in netland could
give me some information about it (Like, what baud rate is it?), cable
pinouts, commands, etc. If someone has the documentation for it and is
willing to Xerox it, I'd really appreciate it (I'll mail you a SASE).
If anyone has already got one working on a 7300/3b1, I'd appreciate it
if you'd mail me instructions on how to do it. (Note: This is a repost
of an earlier article that I believe was lost due to problems with my
newsfeed--if the earlier article did get out, sorry for reposting this)

They are generally 0-300,1200 baud. Some have autodialers in them, and are much less than smart modems (ie. they have little if no "brains" in them). If your modem does have a dialer, it is initiated and ended with some control sequence (I forget it now). The pinout on the "cable" is standard RS232, and should be easy to get hooked to a UNIX-pc. I suspect you'll only be able to use it for dial-in though. You'd be better off using the on-board modem on the UNIX-pc than the DF03. The DF03 really gives you no extra features than the one in your machine already. ------- Gil Kloepfer, Jr. U-Net: {decuac,boulder,talcott,sbcs}!icus!limbic!gil ICUS Software Systems Voice: (516) 968-6860 [H] (516) 746-2350 x219 [W] P.O.

------- Joe, The baud rate is 1200. Gil was correct in stateing that a DF03 has little or no "brains" in them but it is a pretty old modem. To initiate a conversation use ^B. It will not respond but at this point is ready to take a phone number. The phone number is input and as each value comes in it is used (numbers should be presented with apx 1/2-1 second between numbers). It continues to take numbers until no more are presented and then waits for 30 seconds or so for the call to complete. If the call is successful an "A" is returned (for attached) and a "B" (I believe) is returned is busy. The modem uses a standard rs-232 cable. The buttons on the front are pretty much as one would expect. Also there are variants which do not dial (auto answer only). If you try the ^B deal and it does nothing you probably have an answer only modem. Larry --- Larry Palmer Ultrix Networking/AD --- Digital Equipment Corporation --- Nashua, New Hampster --- ...
