If you make use of the instrument driver code here, please note

the Argyll's author(s), and not to any other party.
If there is some instrument feature or function that you
would like supported here, it is recommended that you
contact Argyll's author(s) first, rather than attempt to
modify the software yourself, if you don't have firm knowledge
of the instrument communicate protocols. There is a chance
that an instrument could be damaged by an incautious command
sequence, and the instrument companies generally cannot and
will not support developers that they have not qualified
