For example, have a ``isdn64'' label which only uses one channel and a ``isdn128'' label which uses both channels. Then you could invoke ppp like ``ppp isdn64'' or ``ppp isdn128''. Of course, you'd have to shutdown the single-channel connection first. I'm no ppp expert, so that's about all I can contribute. See the ppp man page and the examples under /usr/share/examples/ppp. --- Gary Jennejohn / garyj[at]jennejohn.org gj[at]freebsd.org gj[at]denx.de
