Many thanks to Harald Pollack for supplying the sources to this neat
TIF TO TIF converter. T2T is an 32b OS/2 2.x EXE compiled with C Set/2.
To convert BT-EE's fax files to TIF files, you'll have to start T2T with
the following options:
T2T -ipage0101.fax -opage0101.tif -x -c2
"-c2" is optional; it writes the same file but with header and TIFF tags.
If your TIF programm cannot read TIFF-F files, convert the file with
another -c paramter; e.g. no -c at all for an uncompressed file.
Have fun
