There is a warning about using the SelfSend option in AppleTalk
because some programs may not expect to get packets from its own
node. In order to avoid this problem I'm resetting the SelfSend
flag to the old value after my calls to AppleTalk. However,
I'm wondering if there is a problem if my calls are async. It
depends on which of the two statements below that is correct.


1. Sync. calls are executed directly before queued calls so there is
a possibility that the SelfSend flag is temp. set by me when other
programs are calling AppleTalk sync.

2. Sync. calls are executed after the last queued call and everything
will work just fine.


Couldn't find the answer in any of the IMs or TNs. So I'm asking you.

Thank in advance
