Presumably you meant 1100 0000 for the value, as your's above is 9 bits.

To output bit-by-bit starting with msb:

         iDiv=2^7
         for iPos=7 to 0 step -1
           iBit=iData \ iDiv     'this will be 0 or 1 for bit in position i
           call OutPort(&H378,iBit)
           iDiv=iDiv \ 2         'shift to next lowest bit
        next iPos
