Console question

[Etienne Fortin]

Hi Eric,
Thanks for the reply. I'm using ICANON=0. I assumed that since I receive
binary data, I don't want any processing on the inputted data. Am I
right about ICANON and that requirement?

Probably.

Are you using cooked (ICANON=1) or raw (ICANON=0) input?  The cooked
buffer is 
not unlimited.
