- The reason for this is that two modems with v.8 enabled will not
- connect using vFC, only with v.34, v.32bis/terbo, or lower.. If you
- disable v.34 with the S56.6=1 command, you can still connect with vFC to a
- modem that supports vFC as it's only 28.8 protocol, but you can not make a
- vFC connection to a modem that supports both vFC and v.34. This actualy
- kinda makes sense when you think of it. v.8 is an ITU-T protocol,
- designed to negotiate the best ITU-T connection protocol that the two
- modems support, it doesn't make much in the way of provisions for
- non-ITU-T connect protocols such as vFC (or HST, or PEP). I think
- v.32terbo managed to sneak in there since it's really just an extension of
- v.32bis, and not a whole new protocol.
