A friend of mine is looking into buying a modem. She found a 2400 baud Supramodem for $149. Has anybody ever heard about this modem or have experience with it? Any information is welcome. Thanks in advance. Owen

My one complaint is that I have occasional problems with line noise. Other people in this area have had similar complaints using other modems, though, and the consensus is that the lines running into the university are bad. Anyhow, 4 out of 5 times I use the modem I have no problems, and on particularly noisy days 1200 baud works fine. I do advise that whatever modem she gets have a speaker so you can listen in. It takes very little practice to be able to predict when a line's gonna be too noisy. Despite what Dave at CMO says, the Supra has a speaker. -- Jeff (martens@cis.ohio-state.edu)

It offers all the features you normally expect of a 2400 baud modem, including nice things like storing one phone number in non-volatile RAM, and storing your preferences in NVRAM as well. You can control things like the speaker on/off/volume and autoanswer on/off through software. That part of it seems pretty compentent, certainly much better than the Volksmodem 1200 the Supra replaced. The modem itself is physically small -- a small bit shorter and wider than a paperback book. The case is metal. The biggest thing I don't like about my Supramodem is that the on/off button is VERY cheesy. It doesn't click smoothly, and usually requires about three tries to turn the modem on or off. Of course, you could simply turn it on once and leave it on. I am thinking about replacing the switch with something from Radio Shack. The other complaint I have about the Supramodem is that it seems to be intolerant of line noise. The phone connection to the terminal concentrators here at CMU has one really bad connection that I occasionally get when I dial in. I don't really have any other modems to compare the Supra against, but when I wind up with the bad connection the modem does get confused pretty heavily. Of course, with DNET this isn't a problem (yet another round of thanks to Matt Dillon). In summary, it is not a bad modem, it does a lot for the price, and I am happy I bought it, but it does have a few problems. -- Michael Portuesi / Information Technology Center / Carnegie Mellon University INET: mp1u+@andrew.cmu.edu / BITNET: mp1u+@andrew UUCP: ...harvard!andrew.cmu.edu!mp1u+ "I'm very sorry, Master, but that WAS the backup system" -- Slave

Yes, Supra 2400 is a good buy. It is "Hayes" compatible (I can't remember the standard). Very easy to use. Works well with Handshake and Access! I recommend it. Roger Mann

It IS more susceptable to noise than some of the more expensive machines. Jerry Pournelle is plagued by noisey lines. He reports his 19.2k modem used at 2400 baud is much better than anything else he has used. (Not sure which brand it was, alas. I didn't bother to check as I can't afford one just yet. <sigh>) My experience here indicates it is a little worse than the Ven-Tel 2400 that I have regarding line noise. It has a much better command set, though. And it costs a whale of a lot less. -- Sometimes a bird in the hand leaves a sticky deposit.

I have been working on writing a smart modem dialer recently and so far have found no Hayes incompatibilities. The documentation is not the best I have seen, but is better than most. I would recommend it as a very good value for the price. -- Kevin McBride Another // | Also: Wang Laboratories Proud // | President, brewmeister, chief taster Desktop Image Systems \\ // Amiga | McBeer Brewery, Nashua, NH ...!ima!wang7!klm \X/ owner | ...!ima!wang7!gozer!klm

I heartily recommend the Avatex 2400; I bought one a year ago for <$200
and have had absolutely no problems. The documentation is absolutely
first rate, and provides every detail in which you could possibly be
interested.

Amid all this praise being heaped upon the Supramodem, a lone voice speaks out... The Supra 2400 baud modem answers with a 2250 Hz tone (for the 1200 baud fallback), instead of the correct 2225 Hz. These tones are supposed to be accurate to within some small fraction of a percent, which this gross error is several hundred times larger than. The net result is that if the Supra is called by some 1200 baud modems (like MINE), a connection cannot be established. Of course I did this research since my modem would not connect to any Supra based BBS's in town. The attractive pricing of the Supra seemed to outweigh any quality considerations when the BBS operators were purchasing. Needless to say, I do not frequent these boards. Our own club's board runs a 2400 baud Promethious(sp?) modem which I have no trouble with. Note that if you are the Supra modem owner, you will have no trouble at all, unless someone wants to connect to you. All this is not really Supra's fault, the chip set being used has a design flaw (shall we call it a mistake?) | // GOATS - Gladly Offering All Their Support Dave Kinzer (602)897-3085| | // >> In Hell you need 4Mb to Multitask! << uunet!nud!fbog!dbk | | \X/ #define policy_maker(name) (name->salary > 3 * dave.salary) |

From article <10035@teroach.UUCP>, by dbk@teroach.UUCP (Dave Kinzer): > ...The net result is that > if the Supra is called by some 1200 baud modems (like MINE), a connection > cannot be established... I used a Paradyne DTU-1200D for a while and experienced difficulty connecting to a BBS with a Supra Modem. I don't know if there was a difference in the frequency of the answer tone, though. What I experienced was one answer tone for 2400 bps. After a few seconds the tone changed. It appeared the Supra was generating an answer tone for 2400 bps, then, if no connection had been made, falling back to a 1200 bps tone. Trouble was my Paradyne modem would time out while the Supra was still sending its 2400 bps tone. I worked around it by dialing manually, waiting for the second tone, and then sending the Paradyne into originate data mode. --Fabbian Dufoe 350 Ling-A-Mor Terrace South St. Petersburg, Florida 33705 813-823-2350 UUCP: ...uunet!pdn!jc3b21!fgd3

Ive never had a message from anyone regarding a problem logging on at 1200 baud. (This may be because they couldnt connect ;-) I don't dispute the incorrect answer tone (I havent done any research), but I do wonder how many 1200 baud modems have this problem. Mostly im curious if this is a common problem or if most modems are tolerant of the tone mismatch in the Supra.

I, too, have been running a BBS for some time using a SUPRA 2400 modem, and I can say there is a problem... ONE person, who has a Volks-64 modem generally cannot connect on the first try. However, a connect 1200 is usually made on the second attempt. Of course, I happen to think that this is a fault of the Volks-64 (a piece of sh*t from all accounts that I've heard) but, it may be due to the Supra. Other than that, no problems, seems to be a good modem. (only.. make your own serial cable!! Supra will cheerfully rip you off selling their "Amiga Package".)
