Guy,
I had a similar issue with another inhouse developed DOS based NT
executable.
But when out programmer put into his C code 'flush STDOUT' after each printf
it got fixed.
So I dont believe it is NT cmd.exe buffering the output of tethereal.
Regards

It doesn't seem to work if you pipe it to "more", either. (I'm assuming
here that the NT shell (cmd.exe) really sets up a Win32 pipe for a
command-line pipe, which it might not do.)
It may just be that the standard C interface that Tethereal uses to
implement "-l" ("setvbuf()" - by "standard C interface", I mean
"interface specified by the ANSI C standard") doesn't actually work with
the MSVC++ C libraries. I'll have to experiment with a small program.
