This is interesting; I've never had a problem with output redirection;
it's supposed to go to the same place that NM's stdout and stderr, which
in this case are redirected to syslog's 'daemon' facility.  NM shouldn't
be trying to proxy pppd's stdin/stdout at all.

Whats in your /etc/ppp/options file?  Unfortunately pppd will *always*
read that file, and options in it take precedence over what NM sends on
the command line (whcih also cannot be changed).
