Dave,
?
As inferred by original post "rig_io::readResponse" -> "/src/support/rig_io.cxx"? and the method "readResponse" line #167.?? Here is a snapshot of my temp fix for issue 1:

Issue 2 - you can see the "do" loop line #175? now exists for both? "read_from_Remote" and "from serial" were as before was only looping for "read_from_Remote" path.
Will leave it up the devs to resolve that one as I have temp solution.
