Again, this >realates to the change mentioned above. I don't think anything actually uses /etc/ethers, so it would be pretty pointless. In later versions of FreeBSD, we provide a BOOTP daemon which can be used for this purpose. >3.)

The mode you want is ICANON off and ISIG on, plus you want to fiddle with c_cc[VMIN] and [VTIME] (which didn't work in 1.0.2 but do now). >4.) Has FreeBSD 1.1 been released yet?
