+Subject: [PATCH] HACK: don't even check for termiox
+
+termiox was removed from linux in e0efb3168d34
+Some more information available in https://www.spinics.net/lists/linux-serial/msg41926.html
+
+Attempting to use the termiox ioctls on more modern kernels results in
+"Inappropriate IOCTL" errors.
+
+While the "right" solution might be to remove the termiox code from the
+linux path, simply not checking for termiox builds a libserialport that
+functions on modern linux kernels.
