Can you try the attached patch on your mac? Because sending data appears to be 
the problem, sending the packet byte by byte is certainly not going to be the 
fastest. With the attached patch, the packet is send at once.

Another thing that's worth looking at are the tcdrain calls in serial_write. 
Just add some extra WARNING or INFO between the write and tcdrain. I wonder if 
it's the write or the tcdrain which taking most of the time.
