I tried the new extIO with HDSDR under wine.
It crashes at start time, see attached screenshot.

As it only uses TCP, not direct hardware access, I think it should work the way I tried it.
The extIO is derivated from a extio_rtl_tcp version that have the same issue.
But there is another version that actually works with HDSDR under wine.
It can be found here: https://github.com/roseengineering/ExtIO_RTLTCP
The HDSDR part works very well under wine.
Only limit is not using direct hardware API access, so staying to network access (I use it successfully with rtl_tcp with the extIO I mentioned).
Can you see if it something can be modified so we get the ExtIO_RSP_TCP working ?
It would add the RSP_TCP extended mode for users like me not using Windows at all.
