+	  puck) or a VSXXX-GA (rectangular) mouse. Theses mice are
+	  typically used on DECstations or VAXstations, but can also
+	  be used on any box capable of RS232 (with some adaptor
+	  described in the source file). This driver should, in theory,
+	  also work with the digitizer DEC produced, but it isn't tested
+	  with that (I don't have the hardware yet).
