is complete before checking carrier. If it's there,
the device supports carrier. If it's not it doesn't.
Add the ``set cd'' command for deciding how soon to check
for carrier, and for deciding if carrier is REQUIRED.
The default has changed: Pre 2.0 versions of ppp waited
for 1 second. Version 2 didn't wait, but this causes
problems with some (few?) modems that don't assert carrier
immediately on reporting CONNECT. The one second delay
is back now and can be removed with ``set cd 0''.
Bump the ppp version number in case this needs to be changed
again....
