Porting AT&T ioctl()'s to BSD???

[egray at fthood.UUCP]

Howdy.. I've got some problems porting AT&T code to BSD that someone
may have some experience with.

I need the ability to flush the TTY input queue, output queue, or both
similar to what AT&T does with ioctl(fd, TCFLSH, n).  I can't use
BSD's icotl(fd, TCIOFLUSH, 0) since it always flushed both queues.

Also, I'd like a way to emulate AT&T's ioctl(fd, TCSBRK, 1) that waits
for the output of the queue to drain.  I suspect BSD's select() could
be used?

Examples and/or code fragments would be much appreciated!
