+- no response from maxim requesting them to update their USB targets to 
+  mbed 5.12
+- making this example for 5.11.5
+
+
+Ever wonder how to redirect standard in/out/error to a USBSerial interface ?
+Using a *MAX32630FTHR board, here you go :)
+
+Connect your favorite terminal, eg., CoolTerm, run the program, scan for any
+new usb serial ports, connect. A USB serial port is not quite a UART so baud
+doesn' matter much.
+
+
+* After many many combinations of IDE's/boards, I picked the Max because I can 
+easily connect my Segger J-Link for much faster traditional debugging than 
+DAPLink working with VisualGDB extension to M$ Visual Studio 2017 Community 
+Edition.
