 <p>This feature requires kernel-level support for CAN (Controller Area
 Network) hardware.  Presently this is available only under Linux using
-the Socket Can subsystem.  The nmea2000 driver of gpsd has been tested
+the Socket CAN subsystem.  The nmea2000 driver of gpsd has been tested
 with 2.6.38 and newer kernels.</p>
 
 <p>GPSD expects your CAN interface to be configured to receive CAN
-data at the nmea2000 baudrate of 250kBit/s.  Here are a few example
-scripts that will set this up:</p>
