/* For the curious, during testing I managed to screw up the
   characher at CM index2, ('2'). So I needed to reprogram
   index2 with the correct character, doh! Anyway, since I
   went to the trouble I'll leave it in the code. I managed
   to find a default CM map at:- 
        http://www.maxim-ic.com/tools/evkit/index.cfm?EVKit=558
   If you download this then be aware that the DEFAULTCM.MCM file
   defines each charmap as 64bytes, the 10 additional bytes need
   to be stripped off as "not used". */
