Remarks

RAM cost: 0 GB

Write data to the given Netscript port.

There is a limit on the maximum number of ports, but you won't reach that limit in normal situations. If you do, it usually means that there is a bug in your script that leaks port data. A port is freed when it does not have any data in its underlying queue. ns.clearPort deletes all data on a port. ns.readPort reads the first element in the port's queue, then removes it from the queue.
