We have a VAX 11/750 running BSD4.3. Since we use a trailblazer (for news),
the message "dmf0: silo overflow" gets printed rather often on the console.
The trailblazer operates at 19.2 Kb and is the only active 'terminal'
when the above message gets printed. 
	Question 1: Is this a serious error?
	Question 2: Is there a way to prevent it?

The next problem is the strange behavior of the ttyh0 line (the first line).
It's a real pain to use that line. Output stops often, ^Q is then needed
to get something more on the screen. (Whenever I get connected to this line,
I use another one).
On other lines this problem almost never occurs.
	Question 3: What is the cause of this behavior?
	Question 4: Is there a cure?
