title: Serial Parity/Wakeup Bit Beginning of Packet
body: <p>The protocol I am working with uses the Parity (Wakeup) bit to signal the beginning of a new message over RS-232 - all other bytes of the message have the Parity bit set SPACE. Packet contains length and CRC... 
  I need to be able to catch the first byte with the Wakeup bit set and then process the packet from the length information in the message itself. 
  I have done this in several application in assembly and c.
  I am moving to C# and just need help in triggering the start of the capture of the message from the Parity/Wakeup bit of the packet frame - 11 bit with 1 start, 1 stop, 8 data and the Wakeup bit. </p>
