What does the motor controller send back?  How does that compare between the LV program and the manufacturer's software?

That is a good question Lynn.

Does the device only receive?

The device sends stuff back when you invoke the "Verify" command (@0V<command>[profile]).  The device also writes back when errors are requested with the @0! command.  I've bolded the rows where the device wrote back to me:

@smercurio_fc - I see.  I'm tempted to try sending 1 char at a time just to see if it clears up my error flag happening during normal operation.  I also agree that it shouldn't matter, but something about the way I'm writing to the motor is causing it to throw an error flag at me about an invalid command and I am simply not seeing it.  Functionality is fine.  My program works just fine, except I have to ignore errors from the motor (which is undesirable).  I'm about out of time I can spend on this though ><.

I think I'm going to send them an email and ask them if there is a reason they send 1 character at a time to the device.
