I have been reading about the wonders of the Telebit, and was curious as to the availability of software for the PC to run a BBS with it. I'd like to be able to use the modem with my Amiga for getting news, and run a BBS with it on my AT clone. Currently I'm using Wayne Bell's WWIV 3.xx software. Is the Telebit compatible with standard AT-style Hayes commands? Loyd Blankenship cs.utexas.edu!nth!loyd (UUCP) Nth Graphics Ltd Austin, TX Disclaimers, etc...

Do not use a Telebit modem on an amiga, that is if it's over 9600 baud. Amiga systems use as a standard US Robotics ONLY! I have never found a 9600 + baud system that operates with a US robotics. US, has promised to upgrade their modems and promise compatibility. Without one, people will not be able to call your BBS, trust me, I use one, and run a bbs.

Perry, you're very very very confused ... Now if what you were trying to say is that BBS owners generally have US Robotics modems and if most of your business is with BBS's, then yes I agree you should get one of those modems. But my understanding with US Robotics modems is that even though they use V.29 there's a couple of funny things they do that makes the modem basically only useful with another USR modem. Of course I'm in nearly the same boat with my trailblazer, but I rest confident in that technically (at least) I made a better choice. Also, I'm a Unix person and Unix sites tend to have trailblazers ... -- <-- David Herron; an MMDF guy <david@ms.uky.edu> <-- ska: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <-- Now I know how Zonker felt when he graduated ... <-- Stop!

I fail to comprehend these statements. Perhaps you mean to say that some piece of software you are running assumes it is talking to a USR modem, and is also incapable of >9600 baud? Nothing about the Amiga, hardware or system software, prevents th use of its serial port at higher speeds, or requires the use of a USR modem. -- Guy Streeter b11!guy@ingr.com ...uunet!ingr!b11!guy

US Robotics COURRIER HST modems use a proprietary modulation scheme which looks like V.29 in the forward direction with a tiny bit of bandwidth down around 300 Hz for a 300 bps reverse channel without echo cancellation. (a scheme like this has been proposed for standardization, and has gone under the temporary name V.asm - asm for asymmetric.) It runs a hacked version of MNP, which you don't really want to turn off. It sounds like a good idea, but it loses because MNP, even for single characters, is just too slow over the 300bps channel. Telebits or ping-pong V.29 modems will give you much better response time. With the Telebit, it can spoof Kermit or UUCP, instead of having MNP fighting your transfer protocol to slow things down. There are a lot of things I haven't explained in this article, but I didn't want to write 5 or 10 pages. E-mail me if you want more discussion on the technical (as opposed to practical :-) merits of various modems. Peter Desnoyers
