// when you dont typecast it the MSB just gets lopped off.
 value_8bit= value;  // truncate long int

  printf( "%c", (int) value);   // print it as a character
I know it sounds crazy but if you take an 8bit value say 65 thats an 'A'
(I have no real idea but it could be any character)
ok so you have:

long value;
value=65;

printf("%d",(int)value);

thats a 2 calls to get the ascii representation of the 65 so a '6' and a
'5';
if you just printf("%c",(int)value); then that just sends a 65 out the
port.
