TerminalPython.py

##Simple Python Script that will interface with WDC's W65C134SXB and W65C265SXB Boards.
##You can use this as a start to customize the interface for your needs.  
##NOTE:  Change Line 14 to have the proper COM port or it will not work!
## Updated for Python 3: change print statements to print functions
## Added recognition for W65C134SXB prompt of '.'
## Removed extra linefeeds from output
