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....
