You could do with a ``link deflink rm'' after the clone to get rid of
the original ``deflink'' and you could probably do with a ``set
enddisc'', although this isn't essential.
If you're getting hdlc errors and are using a pretty recent version
of ppp, ``set log +physical'' may throw some light on the subject.
You may see that the HDLC error is the result of the peer quitting
- maybe the HDLC error is a login prompt ?
