I have an Hayes V-Series Smartmodem 9600 modem connected to my Mac. I can talk to the modem just fine. I want to call our unix host in v32/v42 mode. The host has a Telebit T2500, which will operate at v32/9600bps. When I call, t the modem grabs the second tone sequence presented, then immediately reports 'NO CARRIER'. I've tried everything I can think of. My Hayes configuration is: B1 E1 L2 M1 N0 Q0 T V1 W1 X4 Y0 &C1 &D2 &G0 &J0 &K3 &L0 &P0 &Q0 &R0 &S0 &T4 &X0 &Y0 S00:000 S01:000 S02:043 S03:013 S04:010 S05:008 S06:002 S07:060 S08:002 S09:006 S10:014 S11:095 S12:050 S18:000 S25:005 S26:001 S36:001 S37:000 S38:020 S44:003 S46:002 S48:007 S49:008 S50:016 The standby configuration of the T2500 is: at&n E1 F1 M1 Q6 P V1 W0 X1 Y0 &P0 &T4 Version GF7.00-T2500SA S00=001 S01=000 S02=043 S03=013 S04=010 S05=008 S06=002 S07:060 S08=002 S09=006 S10=007 S11=070 S12=050 S18=000 S25=005 S26=000 S38=000 S41=000 S45=000 S47=004 S48=000 S49=000 S50=000 S51:254 S52:002 S54:003 S55=000 S56=017 S57=019 S58=003 S59=000 S61=150 S62=003 S63=001 S64=000 S65=000 S66:002 S67=000 S68=255 S69=000 S90=000 S91=000 S92:001 S93=008 S94=001 S95:002 S96=001 S97:001 S98=003 S100=000 S101=000 S102=000 S104=000 S105=001 S106:001 S107=020 S110=255 S111=255 S112=001 S121=000 S130:003 S131:003 S150=000 S151=004 S152=001 S153=001 S154=000 S155=000 S157=000 S158=000 S160=010 S161=020 S162=002 S163=003 S164=007 S169=000 S255=000 OK In particular, the combination of S50=0 and S92=1 should mean the tone presentation sequence is v.25,v.32,... I've been trying for several nights now. I'm posting this stuff at 2400bps. What a waste of two fine modems! Anybody got any ideas?

The V-series Smartmodem 9600 uses a proprietary, non-standard fast-turnaround ping-pong modulation scheme above 2400bps. Although some aspects of this modulation are LIKE V.32 (it uses trellis coding and a similar constellation), it is NOT compliant with CCITT V.32 and will NOT communicate with anything but another Hayes modem above 2400bps. This is similar to the situation that exists with the Telebit Trailblazer Plus -- standard up to 2400, but proprietary above 2400. The Hayes Ultra 96 (V-series ULTRA Smartmodem 9600) supports _real_ compliant V.32 at 4800 and 9600. It connects just fine with the T1500 and T2500, as well as previous VSM9600s. This is similar in philosophy to the T2500 -- the Ultra 96 supports both the standard V.32 modulation _and_ Hayes' proprietary ping-pong modulation at 9600. You shouldn't get a "NO CARRIER" when calling a T2500 with a VSM9600; they should in fact connect at 2400bps, which is the highest speed they have in common. -- Toby -- Toby Nixon, Principal Engineer | Voice +1-404-449-8791 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.

The ULTRA, on the other hand should connect at 9600 without problems. Mike an Maurice are only half right. The ULTRA is not the only Hayes V.32 modem. Hayes has manufactured four 9600 baud modems to my knowledge, I have owned three of them. The first is called the Hayes V-Series 9600, I am guessing this is what you have, it uses a proprietary half-duplex ping-pong protocol to simulate full-duplex, it will only work with other V-series modems. The second modem is called the Hayes 9600 V.42, it also uses the V-series protocol (so you can talk to one of these) and it adds V.42 error checking to insure data transmission, latter MNP-4 was added to comply with the V.42 standard (NOTE: V.42 is an error checking protocol and not a standard, the Hayes 9600 V.42 can not talk to other V.42 modems unless they also support the V-series protocol, which none other than Hayes do). The third is called the Hayes Smartmodem V.32, it is a full duplex V.32 modem, it has a 4 line LCD display as well as soft menu buttons, so you can configure any of the modems options via the LCD and buttons (very handy in synchronous operation), or via the standard Hayes command set. This modem can also operate in a leased line environment. The SmartModem V.32 has no error checking, and there are no plans to add any. The last is the Hayes ULTRA which supports V.32, and V.42bis. The Smartmodem is a more expensive modem than the Ultra. If anyone needs one for use on a leased line or in a synchronous environment, please let me know! I have a brand new one I will gladly trade for the less expensive ULTRA or comparable modem. If it turns out that you do have the Smartmodem V.32 or the ULTRA then you should be able to talk with other V.32 modems, otherwise you have an expensive 2400 baud modem (if its the V.42 at least you have some nice error checking ;-) ). Did I get this pretty right, Tony?

I seem to be having the same problem too with my Hayes Ultra 9600 modem. When I dial up to my unix host, (which has a Telebit TrailBlazer) a connection is made, but is quickly lost; the message 'NO CARRIER' is displayed. My modem is connected to a NeXT cube. Is there anyone out there that has a simple answer to this problem? Thank You, Sal Cataudella -- Sal Cataudella Internet: salc@sisyphus.shearson.com UUCP: ...!uunet!slcpi!sisyphus!salc (212) 464-8728

The Hayes V-Series Smartmodem 9600 does not support CCITT V.32 9600, but instead uses "Hayes Ping Pong" modulation at 9600bps. The Hayes V-Series ULTRA Smartmodem 9600, or ULTRA 96, does support CCITT V. For additional information, you can contact the Hayes Support BBS at 1-800-US-HAYES. A pamphlet entitled "FAST ANSWERS about fast modems" explains the differences between their three 9600bps models.

When I call, We have Hayes V-Series Smartmodem 9600 modems here - and ours don't support V.32 or v.42bis - only V.42 which is something different.

Is there anyone out there that has a > simple answer to this problem? I had a simular problem with a Hayes Smartmodem 2400. I think the problem is that by the time the T2500 gets through the PEP tones and the answer tone, the Hayes has timed out. I solved the problem by setting S9=30 and S10=50. Something less might be OK, but this works. Make sure that S7 is not less than 30. S10 must be greater than S9 because the actual loss of carrier that can be tolerated is the difference between S10 and S9. Since I have done this I get 100% connection. -- cjp@beartrk.beartrack.com

CCITT V.42 _is_ the international standard for modem error control! A Hayes V-series Smartmodem 9600 V.42 will connect in error-control mode with Bell 212, V.22, or V.22bis modulation with any other similarly-equipmented modem (V.42 or MNP4). It won't connect at 9600 with any but another Hayes V-series 9600 modem. The ULTRA 96 _will_ connect at 9600 with V.42 error control with modems from other manufacturers using V.32 modulation. > If anyone needs one for use on a leased line or > in a synchronous environment, please let me know!

When you first posted your message to this regard, I tried to reply to you but the message got rejected somewhere along the way -- so I'm posting this reply on the net. If your Smartmodem 9600 is "brand new", please contact Barbara Miller, manager of customer service at Hayes (404-449-8791), to see about arranging a trade for an Ultra 96. > Did I get this pretty right, Tony? Want to buy a SmartModem V.32 :-) Yes, you got it real close, except as I noted above. I must also point out that it is possible to upgrade an original V-series Smartmodem 9600 to V.42bis capability with a simple ROM upgrade; all you have to do is call Hayes Technical Support to arrange it (404-441-1617). It can't be upgraded to V.32 modulation, however. -- Toby -- Toby Nixon, Principal Engineer | Voice +1-404-449-8791 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.

Thanks to all of you that responded. What I have is the Hayes Smartmodem Series 9600 V.42, which will only talk to other Hayes Modems above 2400bps. The reason I got "NO CARRIER" is that I had the register set that says ONLY connect at the DTE line speed. ( Set this trying to force a connection > 2400bps).
