Is this a WinXP PC? If so suggest to try this link:

ftp://ftp.signalogic.com/software/DirectDSP_DSK/

The DirectDSP software also uses parallel port, but it uses EPP mode and is optimized, so it should be a lot faster
than the old TI software that came with the DSK C6711 (6 min for 500 kbytes sounds like a Turtle). My recollection is
that the host-hpi DLL that TI shipped out with the DSK C6711 for some reason did a lot of retries.
