I'll apply your patch, although with a slight modification. I prefer the 
tcdrain #ifdef right where the function is being called, rather than 
redirecting one function to another. I find that confusing when 
debugging.

But the reason why I'm replying to you is actually the TIOCGSERIAL part. 
Can you tell me what's going wrong there? Is TIOCGSERIAL defined on 
Android, but not supported somehow? Maybe the serial_struct struct is 
missing in bionic?

I have just pushed some changes related to the low latency stuff. Those 
will probably need similar changes. So that's why I'm asking.
