OK, see below for some explanations.

Change this to open/binary/no-wait

copy will now return either an empty binary/string or what's available.
So you'll need to do something like:
Buff: make binary! 2048
Until
[
wait serv
data: copy serv
if not empty? Data [ append buff data]
finished-reading buff
]
with finished-reading a function that checks to see if you have got all
data. This for example how the old Rugby does these things.

No, that's just some info you can forget. It is the number that is
assigned to the connection by the OS, but you are handed back (and are
only interested in).... the connection itself.
