very similar source code. Also, the fact the the fork'd telnetd immediately
becomes a zombie clinches my belief that both the bb applet I use and the
utelnetd your using are based on the same exact code.
Lastly, I will assume that your kernel has DEVFS support... ( just mentioned
it for completeness )
Just trying to help anyway I can...
