device per argument rather than the old way of concatenating
everything then splitting the result at commas and whitespace.
Old syntax of ``set device /dev/cuaa0, /dev/cuaa1''
may no longer contain the comma, but syntax such as
``set device "!ssh host ppp -direct label"'' is now
possible.
correctly by invoking the timer to get the value before
displaying the message.
Don't assume that a value of 0 is ``random'' in
``show datalink''.
Make the random value between 1 and DIAL_TIMEOUT rather
than between 0 and DIAL_TIMEOUT-1
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....
