QFX files are yet another graphic file format used to store received fax
images. The .QFX file format is proprietary to Smith Micro Software,
Inc. and is used by the Quick Link II fax software. The QFX file header
is exactly 1536 bytes long. The fax pages themselves are stored in byte
aligned, bit reversed T4 format terminated with 6 EOL's. See CCITT
Recommendation T.4 for full documentation on this coding scheme.
