As bit by bit detection using modulation bifhase?

A Message Forward Frame A forward frame message to a ballast Shall Consist of 19 bits, as FOLLOWS: a) 1 start bit b) 1 address byte: 1 individual or group address bit, 6 address bits, and 1 select bit c) 1 data byte: 8 data bits d) 2 stop bits

A Backward Message Frame A backward message frame Consists of 11 bits, as FOLLOWS: a) 1 start bit b) 1 data byte: 8 data bits c) 2 stop bits

Sorry, "bifhase"? Do you mean biphase?

There's a guy here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1290603255 and here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1290602793

with a seemingly similar problem.
