Looking through _Byte_ and _Infoworld_ and a few other sources I came across a few models and prices: Model Approx. Price -------------------------------------------------- (1) US Robotics Courier 2400 $350 (2) Microlink 2400 350 (3) Qubie 2400 230 (4) 'private label version' of Micom M3124H 300 (5) Racal-Vadic Maxwell 2400VP 435 My main problem is that I'm pretty unfamiliar with these models (except for the R-V, which we have at work) so making an intellegent choice between them is difficult. I guess I should list my requirements: Aside from the ability to maintain a 2400 bps connection through not-the-world's-greatest-lines, the modem must be external and Hayes compatible. This dosen't narrow it down very much, so there are other features which would be nice to have around: a. MNP error correction b. speed conversion (i.e, computer sees same baud rate regardless of actual connect speed) c. call monitering (i.e, busy signal detect) With respect to (a), I know that (5), and (4) have it. Do any of the others have MNP? If so, up to what level of implentation? BTW in case you're wondering (4) is from an Shamrock ad on p.24 of the March 30 _Infoworld_. [ Does anyone know anything about this modem? It looks reasonably good in the ad.] I also know that (b) & (c) are avaiable in (5), but I'm totally clueless if any of the others have them. Is there anything else I should be considering? Can someone comment of quality and support? What about bugs? I seem to recall that there were some heat related problems with the USR Courier 2400 and it had problems talking to other 2400bps modems when it was first released. Were these problems fixed? What should I buy? Are the prices I found reasonable, or can the modems be had for less? What are your experiences with 2400 bps modems? thanks in advance, Christopher Chow /---------------------------------------------------------------------------\ | Internet: chow@tcgould.tn.cornell.edu (128.84.253.35) | | Usenet: ...{uw-beaver|ihnp4|decvax|vax135}!cornell!batcomputer!chow | | Bitnet: chow@crnlthry.bitnet | | Phone: 1-607-253-6699, USPS: 7122 N Campus 7, Ithaca, NY 14853 | | Delphi: chow2 PAN: chow | \---------------------------------------------------------------------------/
