Frankly, while I understand thier motivation, I think it is a great
disservice, to put it as mildly as I possible can.

There is a piece of code that they licensed from Adobe, apparently.  It is
an eexec routine that is a ceexec routine embedded in it.  basicaly, it
flushes the bands back down the appletalk link.  I have not  experimented
much with it.  What I would do, if I had a MAC, is to hook 2 of them up,
run something that captures Appletalk traffic on one, and writes it to disk.
Then I would start Lasertalk, and dump some code,and ask for a bitmap back.
for display.  I would then analyze thebus traffic.  What I suspect is thatyou
will find a download for  a routine called

flushbands.  Study the invokation of it, and you can determine how to use it.
I have a standalone cexec copy of it, I just have never taken it apart to
see what the invocation is, or how it works.  I'd *LOVE* to have a copy
of the APPLETALK transactions captured by the above technique.  If someone
would do it, and make arrangements to transmit it to me, I'd appreciate it
a BUNCH!
