+
+	Windows:
+	Extract the usbser.sys file from .cab file in C:\WINDOWS\Driver Cache\i386
+	and store it somewhere (C:\temp is a good place) along with the usbser.inf
+	file. Then plug in the LPC176x and direct windows to the usbser driver.

+	program, like hyperterminal. [Note for FreeRTOS users - the required .inf
+	file is included in the project directory.]
+
+	Linux:
+	The device should be recognised automatically by the cdc_acm driver,
