I have all this code I got from the Apple Developer site, It all

connected to my telnet server.
So, lets I say I want to send the command "!COMMAND ARG"
Since this:
- (void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)eventCode
sounds like it should do what I want, and NSStreamEvent is an
NSUInteger, do I just break up the command char by char, and send it
to this method?
Um, nope.
- (void)stream:(NSStream *)theStream handleEvent:
(NSStreamEvent)streamEvent
is a method you implement in one of your classes, of which you create
an instance and then set that instance to be the delegate of either
the NSInputStream or NSOutputStream (or both). It is how the stream
object tells you what is happening to the stream (such as the stream
has opened, closed, received an error, etc...).
Since you need to send some data to the remote server, I believe you
will need to use the NSOutputStream method:
-(NSInteger)write:(const uint8_t *)buffer maxLength:(NSUInteger)length
This is from <http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/NSOutputStream_Class/Reference/Reference.html#//apple_ref/doc/uid/20001983-BAJCCBCH

You may want to click on that link, then download the 'CocoaEcho'
sample code that is available there.
