A question for all the modem gurus out there: I'm checking out a used Hayes V-series Smartmodem 9600 V.42 for a friend who is interested in purchasing it. The problem is that I'm having some difficulties getting the modem to connect. I don't know whether the problem is a malfunction on the part of the modem or just an incorrect configuration, because I know very little about >2400 baud modems and I don't have any documentation for this beastie. I'm using Procomm Plus on a PC configured for 9600 8N1. This seems to work at 9600 bps in command mode but when I connect to a local BBS or to a UNIX dialup I receive a CONNECT 9600 but the high speed (HS) shuts off and I get only a 2400 bps connection. I'm still able to use the connection, though, with 9600 set on my terminal. Any help would be much appreciated. Thanks, Sean esp17020@uxa.cso.uiuc.edu

I don't know whether the The Hayes VSM9600 uses a proprietary fast turnaround ping-pong modulation at 9600bps, which is only compatible with other Hayes VSM9600s. Unless you're calling one of these, it will connect at 2400 maximum. If you'd like a list of the more than 400 BBSes around the country that support VSM9600 modulation, call the Online with Hayes BBS at 1-800-US-HAYES (800-874-2937) or 404-446-6336. By the way, the Online with Hayes BBS has 16 lines, all of which have modems which are compatible with the one you're testing (and V.32, too). -- Toby ----------------------------------------------------------------------------- Toby Nixon, Principal Engineer Fax: +1-404-441-1213 Telex: 6502670805 Hayes Microcomputer Products Inc.

First of all, 9600+ bps modems (and 2400s with V.42 or just MNP) are capable of talking to terminals at one speed while talking to another modem at another speed. In this case, your Hayes V-9600 has made a 2400 bps connect, but has decided to report CONNECT 9600 in order to keep the terminal program (which may be watching the number after the word "CONNECT") at 9600 bps. I'll bet that, if you look carefully and the software doesn't hide it, the CONNECT 9600 is followed by a message like CARRIER 2400... that last bit tells you what the real conenct speed is but doesn't trip up software that isn't looking for the code word "CARRIER". DISCLAIMER: I've seen modems that do this; I have been told that the Hayes V-Series works similarly. I don't own a Hayes V-Anything. If you know better, feel free to correct me. -- UUCP: watmath!xenitec!zswamp!geoff | 602-66 Mooregate Crescent Internet: geoff@zswamp.fidonet.org | Kitchener, Ontario FidoNet: SYSOP, 1:221/171 | N2M 5E6 CANADA Data: (519) 742-8939 | (519) 741-9553 "Experience talks... and talks... and talks..."

Actually, if you enable Extended Unlimited Result Codes in a Hayes V-series modem (W1 command), you'll get three result codes: CARRIER <speed> PROTOCOL: <name> CONNECT <speed> In the Ultra 96, we also introduced the S95 register to allow individual control of result codes that appear during connection establishment. One of these (S95=32) is COMPRESSION: <type> and appears between the PROTOCOL and CONNECT result codes when enabled. Yes, there's lots of information! And it gets worse when you're using X.25! -- Toby ----------------------------------------------------------------------------- Toby Nixon, Principal Engineer Fax: +1-404-441-1213 AT&T: !tnixon Hayes Microcomputer Products Inc.

In the V-series, the word ERROR-CONTROL was not present, but not from the Ultra. I have seen several programs (including at least one of mine :-) see the ERROR part of it as, well, you guessed the rest. :-( OK, so maybe it's my fault too, but I think a robust implementation would have avoided the use of the string "ERROR" in any non-error message, as indeed was the case with the V series -- at least on the ones I have access to. It's true that you have to enable W1 to get it, but still.... -- ronald@robobar.co.uk +44 81 991 1142 (O) +44 71 229 7741 (H)

The problem is that I'm having >some difficulties getting the modem to connect. My experience is that you were lucky to connect at 2400. The Hayes V-series (not Ultra) apparently are most comfortable connecting to each other; those who use them for this will usually use nothing else, too! -- Laird Heal laird@slum.MV.COM The world is my office.
