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).
