-  Title:       NXTERM BROKEN?
-  Description: Has NxTerm been broken.  Testing with the open1788/knxterm configuration
-               I am seeing some bad behaviors after scrolling.  Everything looks good
-               until the first call to nxterm_scroll().  After that, some characters
-               are missing on the display (replaced with spaced).
-               NOTE: This may be an issue only with the Open1788 configuration(?)
-  Status:      Open
