Thanks for the Win32 executable, but that file is chartread. Spotread makes more
sense for my application, because I am reading density patches for which I don't
have spectra data for a .ti2 input file and the SpectroscanT hardware in
transmissive mode is only capable of scanning one patch at a time, not a chart.


OK, here is spotread: <http://www.argyllcms.com/win32_spotread_exe.zip>.


That said, using a cloned .ti2 file I did get this chartread to run, using

chartread.exe -t -p -D fake.ti2

and make several patch reads before it went south with this error -


 Patch read failed due to unexpected error: 'Communication protocol breakdown'
 <No start character received by instrument>

then eventually,

 icoms: Write-Read Write failed returning 0x2000


It's impossible to know what happened without a debug trace. I've not seen
such a thing myself.
