Ed,

I have one problem with ppp modem connection. I use mpd for dial-up 
connections, but ng_tty is not working any more and I had to switch back to 
ppp.

With ping -s 960 I'm getting ~0% loss, with ping -s 980 I'm almost always 
getting 100% loss... But: modem TX light turns on on every attempt to send ICMP 
packet.

Dial-up server is Windows 2000 RAS, and I had no problems with it for last five 
years, mostly with mpd but ppp was OK too...

I can't say, was ppp broken before MPSAFE_TTY changes, but in 7-CURRENT days it 
was in good shape.
