The method is to use the method of handles instead of streams.
Use open (in binary mode), read, write, close.
Read the reference manual on these.

You could use flen = filelength(input handle) and read all of the data into
a buffer but then you must be certain in advance that the last byte is the
EOF marker (1A) and not data.
