Hi!

Please reconsider how you build the keyname and keydata strings. You must use 
a ...sprintf() call instead of adding to '0' since that would work only for 
indexes and ports between 0 and 9.

Remember to allocate enough buffer space to accommodate "\\Device\\Serial255" 
and "COM256".

And while we are at it what about /dev/ttyUSB* and /dev/ttyACM* ? And remember 
these device names are Linux specific...
