What you currently do is copy the data into a buffer and
write it then into the port, right?
There is no way to write contents pointed to by a pointer directly,
unless you fetch and write the data explicitly (either by character,
block-wise or in one go).
Could you give some more information? Is the file to big, is the
operation too slow, or is the interface to awkward?
