I've recently received an advert and price-list for Bytcom "Contac" 2400-baud modems. These are V.22bis/V.22 A/B, 212A/103/113 async/sync modems. They're stated as being Hayes-compatible, FCC 15B qualified (suitable for home use), support MNP levels 3 and 4 as an option, and include an "automatic retraining" feature said to improve performance on poor-quality phone lines. They come with a 2-year swap-out warrantee, which is encouraging. I can buy one at a corporate discount rate of $300, plus $90 for the MNP error-correction option if I would find it useful. Has anyone out there used these modems (or other Bytcom modems of any flavor)? If so, how well have they worked out? Have any test comparisons been run? advTHANKSance, dave platt

These are V.22bis/V.22 A/B, 212A/103/113 async/sync I started with one of these a few months ago and went thru several before returning it. It looks attractive, but it did not work too well. The first problem was I got home one night and it was 'screaming', and required power to be cycled to clear it out. It would not answer the phone for anything. The second problem was it would not answer Racal Vadic modems calling in, and they were not willing to fix the problem! My next modem was a Franklin FM-2400 (MNP level 3) for $299. This had a bug which cuased it to answer the phone when in auto answer and a pulse phone was used to dial out on the line it was waiting to answer on. It took me a while, but I got new EPROMS and they helped me with some other problems! If you get a Contac make sure you verify it works in both directions with as many sites as possible. BTW, is anyone using MNP ? It seems like a good idea, but until one gets to MNP level 5 the benefit appears to be only a 10+% improvement. -- Name....: Tan Bronson Company.: Microvation Consultants US Mail.: 20 Sperry Rd Madison, CT 06443 (20)-421-5061 UUCP....: ...{decvax!genrad!teddy,seismo!yale}!bronson!tan

Others are bothered by the delays in character echoing. -- -- Art Zemon FileNet Corporation Costa Mesa, California ...!hplabs!felix!zemon
