Foundation Tool works(TM) from XCode, but even tually fails from CL

Hello all,
   I've written a very basic foundation tool who's sole purpose is to 
save incoming serial data from a cu.foo socket into a log file that I 
create. Real simple stuff here. Oddly, when I run the executable in 
Release mode from within XCode (Apple + R) I get no problems, and it 
merrily logs away to it's heart's content. Whereas when I launch the 
foundation tool from Terminal it logs along until a certain point at 
which the data it pulls becomes null. Anyone have any suggestions? If 
this were a Debug / Release issue it'd make sense to me, but this is 
just how it's being launched. I guess it does raise the question that 
I don't know how it's launched differently, so I'll go about 
investigating that, but hopefully someone might have an "a - ha".

Cheers
Rob
