dle Posted May 16, 2014 Share Posted May 16, 2014 How can I send \xAA\x0D\x00\x00\x00\x00 to a COM port using device write function? I could send that Hex data to a COM port from the COMM monitor but don't know how to send those Hex data from Device.COMPort.write(xxxx) Link to comment Share on other sites More sharing options...
AzeoTech Posted May 18, 2014 Share Posted May 18, 2014 device.myDevice.write(chra({0xaa, 0x0d, 0x00, 0x00, 0x00, 0x00}) 1) remember, you access the comm port through the device its associated with, not by the comm port name 2) {} creates an array (can only contain constants) 3) 0x prefix means that the value after is hex 4) chra() takes an array, and converts it into a string of characters Link to comment Share on other sites More sharing options...
