Didn't UTSL either, but the issue is that the Unix serial driver
is allowed to buffer a character or two which has been acknowledged
as being sent to the application, but is actually not yet sent.
The TIOCSDRAIN ioctl (or whatever Posix calls that) tells the driver
to wait until all characters have left the transmitter.
