I observe that your instrument get's configured to
RTS/CTS hardware handshake. Does your USB-Serial
adapter support this? This is at least against what xrite
sugests, and never worked for me with any USB-Serial
adapter I tried. Can you try with no handshake, aka

The correct approach in the source code is to #undef HWFC.

You may get away with this for the DTP51, but I found some
sort of flow control was necessary for reading long strips
of spectral information on the DTP41, and for some reason
Xon/Xoff was not reliable, whereas hardware handshaking was.
It seemed to work fine with the Keyspan USB/serial adapter.
