Speaking of pauses...while testing a new box with 2 Cyclades 16ye's
running 2.0.0, I had one modem dialed into another and did an 'ls -laR /'
from my minicom session on the terminal server (dialed into same terminal
server and then rlogin'd to the shell host). While doing this, I noticed
that any use of ipfwadm -lA or even just cat /proc/net/ip_acct would
cause ttyC overruns. This was on a P100.
