+Ross NK Video Switchers (via SCP/A Serial Interface)
+
+Driver Name: Ross NK-SCP/A Interface
+
+Supported RML Commands:
+  Switch Take ('ST')
+
+GENERAL NOTES:
+Control is done by means of an RS-232C connection to a NK-SCP/A serial
+interface.  Serial port parameters should be set to 9600 baud rate, no parity,
+8 data bits, 1 stop bit, CR termination.  The Breakaway to use is defined
+by setting the 'Card' parameter in the driver configuration, with
+Card 0 = Breakaway 1, Card 1 = Breakaway 2, etc.
