/* Serial Debug Test
** Version: 0.0.1
** Author:  Jim Mayhugh
** Date:    04/26/2015
**
** The pupose of this short test is to verify the two Serial channels
** used for debug purposes on the TeensyNet are operational.
**
** The IDE Serial Monitor is used on TeensyNet boards prior to Version 14
** The hardware ability to use either the IDE Serial Monitor or 
** alternate Serial2 was included in TeensyNet hardware version >= 14.
**
** When using Serial2, you'll need a USB to TTL serial adapter similar to this:
** http://smile.amazon.com/gp/product/B00F2F5HVK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
**
** With the above cable the connections are as follows:
** Black - GND
** White - RX2
** Green - TX2
** Red   - VCC
**
** Your connections may vary with a different cable.
**
** To test, compile and load this program onto the TeensyNet, open the IDE Serial Monitor, and
** use a terminal program such as Putty or Cutecom to connect to the appropriate device.
** In a Linux derivative, it should be something like /dev/ttyUSBx or /dev/ttyACMx, where x is a number.
** Make sure that the baud rate to both the IDE Serial Monitor and FTDI Monitor are set to 115200
