Using terminal mode with 4.0 on the box, I can connect to the ISP, it says CONNECT 115200, then nothing. When 3.4 was on the box, and with the machine I'm on now (still 3.4 until I get this PPP thing figured out), I get the old-fashioned login: prompt. So it seems there's something about 4.0-RELEASE and ppp on this machine that's causing PPP to freeze up early on so that the login prompt never arrives. The racks do give up the prompt. I checked out the FAQ, and took its advice on recompiling ppp with a couple of added options so I could run the debugger on it. Doing a stack trace when it was sitting waiting, I got this: #0 0x281c1c50 in select () from /usr/lib/libc.so.4 #1 0x8068e71 in DoLoop (bundle=0x808a7e0) at main.c:534 #2 0x8068d83 in main (argc=1, argv=0xbfbffbdc) at main.c:492 #3 0x804af59 in _start () What's going on in usr.sbin/ppp/main.c is beyond me, though.
