Re: Problem in receiving serial data!

[Chris Rake]

UART-based communication (computer COM ports) are formatted as 1 bit
of start, 5-8 bits of data, an optional parity bit, and 1-2 bits of
stop.  If you wish to transmit 12 bits of data, you'll need to send it
as 2 frames (6 bits each) and then reassemble (extract the data).
However you'll need to verify that the micro is formatting the data
correctly (with start and stop bits).
