Netcat is a great, simple tool. But sometimes it's not quite enough for what you need to do, eg when you need to control some of the socket options on the connection you're creating (eg if you're talking to a serial device and need to set line speed or something). For Netcat on 'roids, check out socat. Socat has more options than the Chicago Board of Trade, but once you figure it out a little, it can be very helpful. 9 times out of 10, netcat does what you want, but for that extra 1/10 where you think to yourself "argh I wish netcat could just do XYZ too..." you'll want to know about socat.
