in fact a vb code sends 4 bytes for controlling the for direction of the car!
the byte goes out from the serial port of the pc and goes into the PIC through A0.
then this byte should be outputed on port b of the pic(b0...b7)!

the algorithm is as follows: the pic receives the byte bit by bit through A0.
it stores the byte in a register and then output it on port B

the problem is teh code! can anyone help?
