The TCPClient transport handler allows the delivery of results over TCP/IP to an arbitrary host. This transport handler can be used in both directions, connecting to a server to receive data and connect to a server to publish data.
Options
host: The host/IP of the target
port: The port of the target system
read: The size of the read buffer (optional)
write: The size of the write buffer (optional)
