Chris, Sounds like you pulled a hamstring jumping on the full-duplex bandwagon there… BIMODEM has been available for quite sometime on an MS-DOS machine, but its popularity is not that great, why? Very few people actually have a need for simultaneous data transfer, most of their communications are decidedly unidirectional. It's good to have on the occasions when you need it, but you rarely need it. JANUS is becoming a two-way standard since Binkley 2.40 was released for Fidonet systems. And, even though a high level Fido system does have a need for full-duplex data transfer, you still see Dual Standards on their systems, why? Because the callers that frequent those systems have the one-way file transfers. Since HST mode sends data faster than a V.32 does, they keep it on there. Then, you have to factor in the inertia of all those installed modems. Now that the popularity of the HST on BBS's have caused a good number of callers to upgrade to an HST. They are going to prevent the sysops from switching over to a new and incompatible modem unless there's some way to keep those callers happy. That's why the Dual Standard provides the most sensible solution. Nope, the HST is not going to go away for a good time to come. At least, not until V.32bis modems become dirt cheap. -jack
