/** Functions to control the mbed interface
 *
 * mbed Microcontrollers have a built-in interface to provide functionality such as 
 * drag-n-drop download, reset, serial-over-usb, and access to the mbed local file 
 * system. These functions provide means to control the interface suing semihost
 * calls it supports.
