Thanks all,
This presents a problem for me since I was using some third party
serial port classes (AMSerial, if you're familiar) to do the serial
port stuff. It uses NSStrings in all it's write methods, which is
why I was having such a problem.
I guess I could modify his code, or just use the serial port
samples Apple has posted. I thought there'd be an easier way, as I
don't know much about serial I/O and termios structs. Guess I'll
have to learn : )
Thanks for the help though.

I'm having a bit of trouble trying to convert an array of 7

values to another object that is expecting an NSString that it

(unsigned char) myArray[7];
Hi,
Unless I've missed something, can't you just write it directly,
instead of going through NSString (or NSData)?
write(fileDescriptor, myArray, sizeof(myArray));
