Try something like this. Only works with current experimental versions of
REBOL (www.rebol.com/xpers/xpers.html) though.
peer: open/direct/binary/no-wait tcp://myhost:23
forever [
wait peer
input-data: copy peer
; Handle your data here and insert the response, e.g.
; insert peer #{fffc25}
; The following print is just an example...
print input-data
]
The direct/no-wait ensures that copy returns whatever data is available. Without
it copy usually blocks until the peer signals end-of-file. The wait is necessary
to avoid busy-looping on copy. If copy returns an empty series (#{}) then this means
no data is available (should not happen after a wait). If copy returns none then the
peer has closed the connection.
