The command for reading an encoder position is:
get_encoder encoderName
The command for setting an encoder position is
set_encoder encoderName
After issuing the get_encoder command, it it necessary to issued a command to wait
for the results to come back from the DHS responsible for this encoder. The command that does this is:
wait_for_encoder encoderName
This function should return the value of the encoder when the message is completed, but currently does not. This bug has a work around as described in the bug repository.
