Not able to execute the Step 3 (Modpoll Test) in the Energy meter demo shown in developer website

in RB-A5D2x

Here is the script I have written:

./modpoll.bin -m rtu -a 1 -t 4:float -r 159 -b 9600 -s 1 -P none /dev/ttyS2

Got error as below:

@ruggedboard-a5d2x:/data/meter# sh modpoll.sh 
modpoll: Unrecognized option or missing option parameter! Try -h for help.
@ruggedboard-a5d2x:/data/meter# 
@ruggedboard-a5d2x:/data/meter# sh modpoll.sh 
modpoll: Unrecognized option or missing option parameter! Try -h for help.
@ruggedboard-a5d2x:/data/meter#

Please help!

The correct code line for the script is:
./modpoll.bin -m rtu -a 1-t 4:float -r 159 -b 9600 -s 1 -p none /dev/ttyS2
