That's odd. I am quite sure that was already in JNOS. I didn't
"invent" that. Unless somebody removed it from JNOS?

It's a stretch, but ok. The reason it is a stretch is because this
*is* 'source's only function... that is, to apply local commands
from a file. But 'upload' can be used for sending any kind of
ASCII data across a terminal connection. The example I chose just
happened to be one that involves commands for a "remote" device to
which I am connected, but there are certainly more uses for 'upload'
than just that.

Go ahead and program it if you really need a <session #> parm. I
don't need it so I wouldn't bother with it. 'upload' works fine
for me without it.

You really can't do that. Only one session can be 'current' at a

No, of course it doesn't... but conversely, nothing about session
structure permits sending the same data simultaneously to more than
one session. Just how would you do that?

Sessions don't have to be 'active' (you really mean 'current') to
receive packets. Received data in sessions which are not 'current'
gets tucked away nicely in input stream socket receive queues until
the session is made current and the data can spill out to the 'user'
in the session screen.
