I have a Hayes Ultra 96 modem connected to a NeXT cube, running kermit. I cannot connect to ANY modem at speeds greater than 2400 baud. I even tried the Hayes bulletin board and had problems with that. The symptoms are either a quick loss of carrier, with the message 'NO CARRIER', a connection is made and then the modem just 'hangs'. I have tried several sites known to have Hayes Ultra 96 modems, and could only connect at 2400. The problem is even worse if I try to connect to a Telebit TrailBlazer modem. Although I can connect to the Telebit using a Hayes compatible modem (ViVa) at 2400 baud, for the life of me, I can't get the Ultra to successfully connect at any speed! Is there anyone out there that has experienced the same problem(s) with an Ultra? And found a solution? Could it be the serial cable (is a special cable needed for the Ultra) ? Kermit? the NeXT cube? Any help would be greatly appreciated! Sal Cataudella -- Sal Cataudella Internet: salc@alfred.shearson.com UUCP: ...!uunet!slcpi!alfred!salc (212) 464-3871

I tried to mail this, but it bounced.

It's highspeed mode is a Telebit proprietary protocol called PEP. Telebit also sells the T2500 which supports both V.32 and PEP, and the T1700 (I believe) which is V.32, but not PEP. You should be able to connect at 2400. Thanks for your response though; It appears my problem is that my modem is NOT an Hayes Ultra, only a V-Series 9600 and is therefore not a true V.32 modem.
