That still doesn't explain why ppp sticks around after it declares the bundle closed due to lack of LQR replies... surely that's basically equivalent to detecting carrier loss? :) I'll increase the debug level and perhaps try an earlier version too, to see if that changes anything. BTW, the modems have been working fine with pppd... BTW2, although I'm having this particular problem I'm otherwise impressed with the stability and relative ease of setting up the multilink connection - mpd looks similar but I figured user level ppp was probably better supported. This is the initial test for a future set of (up to) 4 x 33.6k links.
