Hi, I was wondering if anyone out there has had problems connecting to USRobotics V.32 modems with Hayes V series 9600 modems??? I am using the Hayes to origiante and the USRobotics to answer. The Answer end is controled by Wildcat, and works for other USR modems. When I try a connection I get connected at 2400 with error correction (V.42bis I presume). I've tried locking the Hayes to 9600, then I just get NO CARRIER. Is there anything special I have to do to either modems, the USR is set to try to detect V.32 AND HST modulations. Any ideas??????

The Hayes V-series Smartmodem 9600 uses a proprietary, non-standard, fast-turnaround half-duplex ping-pong modulation scheme. It is _not_ a CCITT V.32 compliant modem, any more than is the USR HST or the Telebit Trailblazer or the Microcom AX/9624c. All of these use different, incompatible, non-standard modulation schemes. The highest speed in common between the USR V.32 and Hayes VSM9600 is 2400bps, which is why they connect at that speed. If you want to connect at 9600, you'll need to have a Hayes Ultra 96 (V-series ULTRA Smartmodem 9600), which _is_ CCITT V.32 compliant. -- Toby Nixon, Principal Engineer | Voice +1-404-840-9200 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.

I've seen a lot of modems based on V.29FT; do you know how compatible they are with each other? -- UUCP: watmath!xenitec!zswamp!root | 602-66 Mooregate Crescent Internet: root@zswamp.fidonet.org | Kitchener, Ontario FidoNet: SYSOP, 1:221/171 | N2M 5E6 CANADA Data: (519) 742-8939 | (519) 741-9553 The mile is traversed not by a single leap, but by a procession of coherent steps; those who insist on making the trip in a single element will be failing long after you and I have discovered new worlds. - me

Most of the V.29FT modems I've seen are synchronous-only (used on fast-poll multidrop leased lines). I don't even think Microcom's MNP6 modems can use their high-speed modulation synchronously, so they wouldn't be compatible. As for whether the various V.29 fast train synchronous modems are compatible, it would be "de facto", based on some manufacturers following others, because V.29 itself only defines the (approximately) 250 msec long train. -- Toby Nixon, Principal Engineer | Voice +1-404-840-9200 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.
