The question was asked more than 5 years ago, but on the off chance that a future explorer might have the same problem:
The Prologix unit must be put into the "DEVICE" mode to use the "status" command. If the Prologix is in the "CONTROLLER" mode, the "status" command is rejected as noted in the original posting.
"++mode 0" puts the unit in to device mode (where a subsequent "++status" command will be accepted)
"++mode 1" puts the unit into controller mode
Have a great day!

Additionally, the ++status will not give the response of the instrument, but rather the Prologix device. Use the Prologix vi that I released here to help.
