Yes, I have CD and DSR following carrier; carrier does drop when the line 
disconnects (I put a breakout box on it to make sure; also the same 
config worked fine on Linux...)

I actually added code to pppd to see if the HUP is delivered.  It isn't 
invoking the trap routine when the modem dies; I guess the HUP is somehow 
getting lost in the sio driver?

Yeah, I tried it with both detach and -detach; no effect.  Serious 
bummer, that!! :-)

Thanks,
