- The Sportsters 14.4 doesn't support on-line fallforwards, so
- you'll never see them. This features is only supported in the Courier
- line and in 28.8 Sportster (I think the 28.8 Sportsters also support
- fall-forward in v.32bis mode, and I know they support it in v.34). The
- only way this modem can go back up to 14.4 is if it retrains.

- Fall-forward is a requirement of the v.34 spec, but it's an
- optional feature for v.32bis.
