I've been playing around with ADSP lately.  Things are working fairly
well - ADSP sets up the connection and sends data back and forth just
fine.

My problem is that I'm trying to track a mouse drag on a remote machine.
So as I'm dragging the mouse I send the mouse delta's over ADSP. 
The problem is that these seem to get buffered up on the sending machine
while the mouse is down.

This doesn't happen all the time, some seem to get out, but the majority
show up on the remote machine after quite a bit of time (relatively
speaking).

The data does eventually get through, but not close enough to real
time for my purposes - oftne MANY seconds.

This is running on LocalTalk, but there is no other network activity
on this net (located in my house).  I'm setting eom = 1 & flush = 1
for each chunk of data that I write.  My send and receive buffers
are both 1K.

Anyone have any ideas what's going on?  I'd appreciate any insights
you might have into this behavior.

P.S.  Please don't tell me I have to go back to ATP to get "real time"
network performance...
