Hi,
The attached message got lost in my intray :-/ Sorry.
You say that with debug enabled, ppp thinks everything's ok. Does
this mean that ppp is reporting the modem carrier status as being
``online'' ?
If this is the case, then I suspect a hardware failure - it's
unlikely that the sio driver would report carrier if there isn't
any.... all it's doing is an inb() when it's given an
ioctl(,TIOCMGET,).
