terminate the string by a newline.
inbuf your input buffer from the use context:
read [
append inbuf copy port
if found? find inbuf newline [
do copy/part inbuf find inbuf newline
remove/part inbuf -1 + index? find inbuf newline
]
]

Nothing. Every connection gets a client port with this handler from the
server port. That's the beauty of it. And multiplexing is done by a
state machine based on the event per port, hence the name "async".
