So make sure the buffer in which the process writes is unibyte with

    (set-buffer-multibyte nil)

and make sure Emacs doesn't try to decode the process's output:

    (set-process-coding-system <proc> 'binary)

(which you can also set directly when you launch the process, but how
you do it depends on the function you use to create the process).
