change the gpio state immediately

how can i change the state of gpio on digi connect me 9210 with plug N’play firmware immediately. I can change the initial state of gpio thru web interface, but if i want to change the state of them, how can i do? which command i should use. I have read the “Digi Connect® Family Command Reference” throughout but I cannot find the command.
my work device :1. DE-ME4-01T-S 2.A supportboard
