Okay, I got everything working using the NSData objects. I'll try encoding the bytes again with the unint8_t* cast. I don't know why I didn't try that... I'm really not very comfortable when it gets down to this low-level stuff. I'm a musician, and my programming experience came from MaxMSP, to Java, to Objective-C, and now to this basic C stuff. In other words, totally backwards! ;-)
But I can make stuff work most of the time (really, I swear!).
thanks again.
