Hi St├ęphane,

If you look in example 2.1, the main machine has the null character on 
the end of its pattern. That's why in that example the driver sends the 
null character by adding one to pe. I'm not sure what else could be 
wrong. When I remove the + 1 from the setting of pe it seems to work okay.

[age at reaves] tmp: ./tmp O C O
Step 1: input O, current state 0... New state is 2
Step 2: input C, current state 2... New state is 0
Step 3: input O, current state 0... New state is 2
result = 0

Cheers,
  Adrian
