Batch Script to turn on/off via serial com port epson projector EB982W
Hi Everyone! I have been working on a script to turn on or off a epson projector EB982W, with no luck. They say in there documentation that they support esc/VP21 commands and the command to power on/off are PWR ON or PWR OFF. more info can be found at this link: https://files.support.epson.com/pdf/pltw1_/pltw1_cm.pdf I found a blog on stackoverflow: https://stackoverflow.com/questions/29259471/how-can-i-turn-my-projector-off-using-command-prompt-or-powershell that specifies how to open a port and send commands with powershell as so: $port = new-Object System.IO.Ports.SerialPort COM4,19200,None,8,one $port.open() $port.WriteLine("<command>") I have also tried $port.Write("<command>") the port opens successfully but the commands are not received by the projector. I would like to note that I have successfully sent commands with mobaxterm, proving that there is no hardware problem etc. Does anyone have any experience with this, direction, solution or advice. I have already taken advice from numerous people without any success
