tcdrain won't work?

Hi, I tried to use tcdrain to make sure that all characters are sent via a COM port but it seems that it won't work in about 50% of the calls to it, i.e. tcdrain returns before all characters are sent via sio.c. Has anyone noticed that effect? I tried to understand how it works. Apparently tty.c
