[BusyBox] [ANNOUNCE] utelnetd-0.1.1

[Glenn Heard]

Hello,

	I had the same problem on my bb system when I was trying to use the telnetd patch with /dev/ptyxx. Mine worked a lot better when I defined a devfs system and made sure that /dev/pts was mounted. This worked, so I went away happy without having to know why the old /dev/ptyxx method didn't work.
