1afa2e8391 Replace previous fix with less agressive, just return EIO 
if ttywait can't drain queue.

1ebc44d8a6 1. If some output still present at the end of ttywait, kill it. 
2. Even if ttywait() fails, call ttyflush(FREAD) in ttywflush.
This two fixes guarantee that queues are empty after calling ttywflush()
in any case

fe0106ed7b Remove the evil I perpetrated on this file in the name of the Cyclades driver, 
now we're back to the old way.  By way of amends, I cleaned up all the
casting evils and generally neated this file up as much as possible.  It
still, however, needs to die.

54d8522bec Turn on "Capture Effect" avoidence. This modifies the collision algorithm 
so that the interface won't have the effect of blocking other senders
during bulk transfers (i.e. hogging the ethernet). It improves performance
in all of my tests by reducing collisions and I believe it to be a Good
Thing.

72af2aa44a Merge Transaction TCP, courtesy of Andras Olah <olah@cs.utwente.nl> and 
Bob Braden <braden@isi.edu>.

NB: This has not had David's TCP ACK hack re-integrated.  It is not clear
what the correct solution to this problem is, if any.  If a better solution
doesn't pop up in response to this message, I'll put David's code back in

forward either (TS_ISOPEN will never be set again for the current
open).  This bug was observed in 1.1 and was fixed in 1.1.5.
