(You can find further information in comp.org.fidonet. Also, there is a LONG article in there detailing all the various modem standards (frequencies, fallback strategies, Hayes commands, etc) including various European standards. Some parts of the article looked to me like he didn't quite understand, but overall it was pretty good. You can get to the FidoNews issue containing these with the "p" command in {v,read}news. -- John) FidoNews 4-19 Page 23 18 May 1987 Ryugen Fisher What's Hopp-ening? ... Recently, there have been many questions about the new 9600 baud modems. Some of you may have them, most do not. Of course, those folks that do have them are anxious to see them on the weekly nodelist, and I can not blame them for this. At the present time, the 9600 baud modems are not listed on the "official" nodelist although Mr. Mike Johnson (Tulsa) is preparing a list of 9600 HST modems that you can add with XLATLIST to the official list if you have a 9600 HST and wish to try to link with someone else that has one. Many people have asked why the 9600 baud modem is not on the official list, and explaining that is the second reason for this column. The first reason that the 9600 baud has not become a "standard" is that Fido, in any of its versions currently available, will NOT work at 9600 baud. Opus and SEAdog will handle the 9600 baud throughput, but Fido just won't do it. I'm sure that you will agree that this is an important consideration. We hope that as the new Fido 12 and Opus 1.XX finish their testing, more sysops will change to one of these systems and thus support 9600 baud modems. But, while software development is one issue, it is not the only (or even the major) one. The major issue is compatibility. Simple put, unlike the 2400 baud modem that was designed to a standard so that Hayes and USR and Multitech, etc could all produce a modem that could and would talk to another brand, in the evolving world of 9600 baud modems, there are not two brands of reliable modems that can talk to each other at 9600 baud. Nor do all the brands "step down" to a slower speed in the same way. What this means is that a U S Robotics 9600 HST cannot connect with a 9600 Telebit and neither of them talk to a 9600 Microcom. And such major modem manufacturers as Racal Vadic, Hayes, Anchor and Multitech have not yet even released a product! But, they are going to. And as each of them is released, we will do our best to test and evaluate, hoping that a common industry standard will soon be reached. When that happens, when two diverse brands of modems are able to repeatedly connect with each other at 9600 baud and can pass the committee's other tests, you can be certain that you will read about it HERE before you see it in PC WEEK or INFOWORLD. What we are hesitant about is that at this time the FidoNet network is the largest network in the world and our adoption in the nodelist of a "non-standard" modem might well (artificially and prematurely) serve to create a "defacto" standard that actually RETARDS the development of a really great 9600 baud modem. At this time, NONE of our testers were willing to spend their $$$ on the products. And as long as that remains true, we can not, in good conscience, actively or BY IMPLICATION encourage you to purchase a 9600 baud modem. -- Copyright 1987 John Gilmore; you may redistribute only if your recipients may.
