Bit convention note (C/P from wapo source) , and meltro correction
        ------------------------------------------------------------ 
         NOTE: For RS-232, the output is normally low.
         We must drive it high for start, stop, or data bits.
         Using 115,200 baud, 1 start bit, 1 stop bit, no parity bit.
         Order of bits sent is:
         Start, LSB.....MSB, Stop
         NOTE: For ATR message (from CAM to IRD at ~12,097 baud):
        
         Bits are inverted (1 vs 0), i.e. if you want to send
         a 1 then you drive the pin low.
         1 start bit (always 1, which is 0 volts),
         8 data bits,
         3 stop bits (always 0, which is 5 volts), 
         no parity bits.
         Order of bits sent is:
         Start, MSB.....LSB, Stop
         This is backwards from the way RS-232 does it.
         Bit duration is 82.7 uS
         Byte duration is 992 uS
Vielleicht ist das wichtig..hab zu wenig Ahnung von der Technik....
