That is absolutely correct... and with the U4K, you DO NOT WANT a Line-Feed! 

The [CR] causes the U4K to execute the command, then the [LF] makes it put 
the command back into the buffer. Next time you issue another command, it will 
see *two*: the old one, then the new one appended to it. Not good. You only 
want to send [CR] to the U4K for proper functionality.
