Return command : OpenX, CloseX (X = 1/2/3/4/5/6/7/8/A)
Example 1:
Send command ''AT+D1=0010'', Channel 1 is ''Open'', after delay of 10 seconds, channel 1 is ''Close''
Send command ''AT+D2=0100'', Channel 2 is ''Open'', after delay of 100 seconds, channel 2 is ''Close''
Example 2:
Send command ''AT+L1'', Channel 1 is ''Open'', other Channels is ''Close''
Send command ''AT+L2'', Channel 2 is ''Open'', other Channels is ''Close''
