The subject really says it all. Does anyone have any recommendations
for good, inexpensive 2400 baud modems?
Thanks,
Geoff

Sounds good. Is it 100% Hayes-compatible? Does it work with the America Online software? (I may be looking to replace our old barely-compatible-enough-to-beep Avatex 1200, which dies the ignoble death with AOL). I'm sure that for that price it doesn't support MNP.

Can you use any modem for the mac that has an rs-232 interface? You just need to get the correct cable right? Do they sell SE's DB-9 to a RS-232 connector to use with those cheap PC external modems? What's this MNP thing with the modems? It's something to do with error correction I hear. Can a non MNP modem communicate with a modem that has a MNP feature(e.g. for a Bulletin Board)? thanks -chung

Just a thought for those considering 2400 baud modems. I bought a Hayes micromodem ][ when accoustic couplers (apple-cats) were the in thing on the Apple ][. I then replaced it with a hayes 1200. I kept it until I bought a Mac in '86, when I bought a Practical Peripherals 2400. Now the PP is sitting on top of a new box that I just got on eval. It is from Telebit and it is called a T1000. It is a PEP modem that does up to 9600 baud (error corrected) over regular phone lines. It is also a 2400/1200/300 modem when you need to connect to slower stuff. Among its many nice features is a special file transfer protocol support--speeding up Kermit, X/Ymodem or uucp tremendously. It also does level 4 MNP at 2400 baud. The best news of all is the cost: $599.00. So before you buy that 2400, give this some consideration. Of course, in another year it will be the T10,000 etherbaud modem only to be outdone by the hyperspace-modulator in '91... Perhaps someone else could talk about US Robotics 9600baud + product line? --ams p.s.

I own 2 T2000's bought before there was a T1000, and I'm glad I had 'em, but I wouldn't recommend them now, certainly not for a Mac. Like the 1000, they only work at 9600 with another telebit, 'cause they use a non- standard protocol. The protocol is half-duplex, so it's pretty terrible for interactive stuff. Uucp and kermit blaze right along, though. These days, you ought to be looking at V.32 modems, since that way you can talk to lots more machines. These will be getting pretty common as prices come down. I knew this was going to be true when I got the Trailblazers, but I also knew these would pay for themselves in the year or so it was going to take for it to become true. (I do a lot of uucp work, and the 'blazers had become the modem of choice among systems doing uucp).

We have approximately 15 Promethius and they all have this problem. People in our department who have them at home have the same problem. For no apparent reason, these modems spontaneously disconnect and you usually can't reconnect unless they are power cycled. If Promethius or anyone has a solution (besides getting rid of them and getting modems that work like they're supposed to), send me email, rjudy@cs.umass.edu, we'd be more than glad to hear it.

The Saga of the ZOOM Telephonics 2400 baud modem A few months ago, I ordered a ZOOM 2400 baud modem. It was a nice little black semitransparent box with LED's behind the front and a volume control on the back. It has worked just fine, done everything I wanted it to do, and I have been quite happy with it. Partially on the basis of my good experience, the institute bought several of these modems. When they arrived, however, they were clearly different from the one I had bought. For one thing, the volume control was missing, and the hole in the case instead gave access to a line impedance trimpot. A virtual volume control was provided in software, so that was not a big deal. Much more serious was the fact that the modems did not seem to be able to send a long break. This is important to us, as we have several DEC terminal servers listening to modems on phone lines to provide dial-up capability, and break is the default way of escaping to the terminal server prompt. We called up ZOOM, and there are indeed two different modems. The one that I had ordered contained a TI chip set, and the later version that the institute ordered contained a Rockwell chip set. Sure enough, if you open the case you can see the logos on the chips. ZOOM has exchanged four of our Rockwell modems for TI modems, and they will exchange the two others when sent to them. They have also claimed that if we order new modems and specify the TI chip set, that's what we will get. We were not able to get any promises that TI chip set modems would be available in perpetuity. So, the moral of the story is, IF you buy ZOOM modems and IF break is important to you, make sure you get the right ones. Better yet, call them and explain why long break is an important feature that they should support in all their modems.

These will be getting pretty common Not that I can afford one yet.... I've heard about V.32, and the new MacUser has an interesting comparison of all of the V.32 modems on the market, but I haven't seen any mention of downward compatibility. I understand there were two or three `standards' for 9600 baud over the past few years, including Telebit and US Robotics HST (?). Considering that the current installed base is weighted toward these standards, is it worth a person's while to wait until V.32 gains a little more market penetration, or can the modem talk to one or both of the previous standards? -- Ralph Brandi ralph@lzfme.att.com att!lzfme!ralph Work flows toward the competent until they are submerged.

The best news of all is the >cost: $599.00. I just spoke with the people at telebit this afternoon. You might want to be on your guard about the PEP 9600 bd protocal. The modems great for communicating with other t1000s and all other telebit modems that use PEP. But, only telebit uses pep. The standard 9600 bd protocal is v.32. The vt2500 (i think) is the telebit modem that uses standard v.32 protocal and costs nearly twice as much. -- Byebye Neal Harrison silb@tank.uchicago.edu

I have been using a Prometheus 2400G for, let's see, about two years now, and I have had no problems of any sort, far less the problems you describe. The fact that all your modems have this problem leads me to believe that it must in fact be something in your local environment that is causing the problem. Perhaps you are all using software that doesn't interact correctly with the Prometheus in setting the baud rates to be used. Have you tried a variety of terminal programs? Have you tried taking one with you on a business trip to another part of the country and seeing if you have the same problem? It's possible you got a bad batch of modems, in which case I believe there is a warranty. But the fact that all your modems exhibit behavior which I have not seen and which I've never heard of from other Prometheus users really does lead me to believe there is some local environmental factor behind this mess. -- Tim Maroney, Mac Software Consultant, sun!hoptoad!tim, tim@toad.com These are not my opinions, those of my ex-employers, my old schools, my relatives, my friends, or really any rational person whatsoever.
