I'm working on a Serial communication program that will talk to an existing system. the system is set up as the following:

baudrate: 19200
stopbits: 1
parity: none
databits: 8

11 bit data packet consist of one start bit, eight data bits, a ninth "wakeup bit", and one stop bit. The parity bit can be used in place of the wakeup bit.

if I were to send:
"10100000001"
databits: "00000001" last 8 bits
wakeup bit or parity bit: "1" 9th bit
stop bit: "0" 10th bit
start bit: "1" 11th bit

Is this correct?

Correct or not? It totally depends on a device and a program on the other end of your serial cable. :-)

Could be a very good help for the one who does it in C++. My 5.

Thanks Sergey - OP is either implmenting an UART (and wouldn't need to ask the question), or really needs a bit of information ...
