Not to be annoying, but here is some more information.
I am opening the Ethernet port async. My notifier receives two events
T_OPENCOMPLETE followed by T_BINDCOMPLETE. No other events come in. I
send out three packets (broadcasts) looking for responses. I see the
responses on the wire (looking from another machine) but they never get
recieved on the sending machine. If I get DHCP to acquire an address, or
set AppleTalk to Ethernet, it starts working.
Thanks for any help,
...Duane
