Any window that requires attention from an operator is going to be a Modal Window. A status bit has been added to the Flags in the UART Status Sub-Command to indicate anytime a Modal Window is open.

The intended use for this is to notify a PC application anytime the XL controller needs attention. This allows the XL user interface to be buried and accessible through a KVM Window Application on a PC. In theory this allows an XL to be installed on a system where its only access to the XL display and keyboard is through a KVM interface window. A monitoring application can monitor the status bit and indicate on the computer screen that the XL requires attention.

This bit becomes available with Eclipse UART version 3.61 and higher.
