Does anyone have any experience with Smart (eg autodialing) high speed synchronous modems. I know of the Hayes/USR 9600 bps async units, but I want to replace our UDS 9600A/B's with a more versitile box. Seems like a natural product. These big modems already have so much in them one would think a little Hayes type smarts would be available. Richard Marks 215-542-2139

[Line eater?!? WHAT line ea
The Telebit Trailblazer (or whatever they're calling it now) does
autodialing and just about every other Hayes command you care to name.
Try calling Mike Ballard at Telebit (408) 996-8000 for more info.

While I don't have any experience with these modems, I would like to point out that it appears that they do not conform to the CCITT V.32 standard. That might prove to be important in your selection process.

Neither the Telebit Trailblazer nor the US Robotics HST are *synchronous*. They're both asynch only modems. I have used both, and must warn that they're not the panacea which marketing literature may indicate. Each has it's idio- syncrasies, which we can discuss over net mail, if you're interested. They do work, and are quite useful. It's just early in the low-cost 9600 cycle, and the emptor should caveat. BTW, I am a participant in Fidonet's testing of these modems, and would direct you to Bob Hartman (..!tektronix!oresoft!dawggon!bobh) for a collection of the general Fidonet consensus on these puppies. -- Randy Bush, Compiler Group, Oregon Software, Portland Oregon (503) 245-2202 uucp: ..!tektronix!oresoft!randy Telemail: RBush Fidonet: 1:105/6

Although the original reply was obviously confused, Telebit does in fact now have a synchronous version of the Trailblazer. We evaluated one, though we didn't have the means to test the synch mode much. It is half duplex, using Telebit's proprietary PEP encoding. Assuming they didn't break anything, it should work about as well as the asynch mode: tempermental but functional. The Racal Vadic 9600VP will also do 9600bps V.29 half duplex synchronous. Several vendors now offer V.32 full duplex synch modems for $2500 and up. But the limited experience I have with V.32 suggests that Telebit's PEP remains far and away the most reliable encoding mechanism over arbitrary phone lines. <csg>

I've had some trouble with 2400 baud connections to a few nearby unix sites, but as we don't have a 2400 baud modem to compare with, I can't say that this modem causes the problem. 9600 baud is very strange. I can reliably connect from A to B if A and B are both at the same site. I can reliably connect from A to Chicago (USR tech support) and from C to Chicago, but not from A to C, even though C is only 10 miles away from A. I have *never* been able to connect A to C at 9600. USR Tech support is very confused (me too!). We're attempting a pile of modem swaps. There are a few things about the modem design that may be important. Most important to us is that, with all of its flexibility (3/12/24/9600, with and without MNP), it REALLY needs an option to force a return to a default pile of settings after each connection. Otherwise, there's no way to use a single modem for both dial-in and dial-out in a reasonable way. For example: to make a call to a non-MNP modem, you must disable MNP before dialing. But since UUCP (and every other modem-program I've heard of) has no post-call string to send to the modem, the modem is left in non-MNP mode. Thus, the next person dialing in can't connect if they need MNP (and 9600 baud *requires* MNP!). The modem has a speed translation feature: you can set the computer connection to any fixed speed you like (up to 19.2K baud); the modem translates everything and buffers it as well. We disabled this rather quickly: adding another layer of buffering in the modem makes it very hard on the poor user who wants to terminate a directory listing, or whatever! I can see that it might be nice in some situations, however. There is one other brain-damaged aspect: the '+++' command-mode aspect KILLS THE CALL IN PROGRESS if MNP is active (as it must be for 9600 baud). This is stupid. In terms of user-friendly other features, this modem is great. It has on screen help, Last-call statistics (counts of chars sent/rcd, errors, hangup reason, call time, etc).... SUMMARY: If I could call at 9600 baud from A to C, I'd be a lot happier. USR thinks others are not having our problems. If I could set the modem to reset to its defaults, I'd be REALLY happy. -- OOO __| ___ Peter Holzmann, Octopus Enterprises OOOOOOO___/ _______ USPS: 19611 La Mar Court, Cupertino, CA 95014 OOOOO \___/ UUCP: {hplabs!hpdsd,pyramid}!octopus!pete ___| \_____ Phone: 408/996-7746

It is the same thing as the Courier 2400 with even more features, including MNP. b) It works very well at 9600bps. I've made a limited number of LONG DISTANCE calls at 9600 and it worked everytime. I have downloaded files from a local bbs with the HST that have exceeded 10100bps. Over all, I've been using the HST for 3 months with no problems AT ALL. I know of three other HST's (operating on local bulletin boards) that have the same record, and over 200 Fido compatible systems are running them. --- Marc Randolph ...!rutgers!pbox!mfbbs!marc

They are not as annoying as the problems with the Telebit, but they are annoying. I can connect to Europe sometimes, and other times can not get 200 miles. Yes, it would be wonderful if the HST (and Telebit) would revert to the EEROM settings when the call is finished. Note that the Telebit reverts to *factory* (not EEROM) settings if an outbound call collides with an inbound call. This is usually very confusing to the software. Also rumors that hundreds of Fidonet systems use HSTs are rather overstated, to say the least. Currently a few dozen Fidonet systems use 9600, and they're about half USR and half Telebit. -- Randy Bush, Compiler Group, Oregon Software, Portland Oregon (503) 245-2202 uucp: ..!tektronix!oresoft!randy Telemail: RBush Fidonet: 1:105/6

We have a new Telebit TrailBlazer on ames and have it set to revert to the EEROM whenever DTR drops. As DTR should drop after every call (if it's an incoming call, the DTR will drop when uucico exits, and go high again when a new getty starts; if it's an outgoing call, uucico should drop DTR when it's done -- if not, it's broken) we have no problems with default settings. Having an incoming call collide with an outgoing call is always confusing. The other side is expecting login and we're sending ATDT.... Steve
