Messaging
The messaging command is used to send a popup message on the device's screen. this allows to cmmunicate with the users.
Note that you can define the message to be a question. In that case, you could link the next command with this question in order to pass on the decision of the execution of the next command to the remote user.
You can set the display time of the message or the question. if it is a question and the question does not get an answer after the display time, then the next command will be automatically executed.
For example, the question could be: " Dear user of this end point, we are need to update your application and this requires a reboot. can we proceed now ?" if you link the question command to the next command, then if the user says NO, the next command will not be executed, and if he says YES, then the next command will be executed.
