[QUOTE="MTBikerTim, post: 268152, member: 54432"] I finally got something working reliably for this. It's taken me just a little while to get around to it. Here is the code I have currently for it. It's not the best code and I apologise for that now. I'm sure it could be done better too, I'm a noob what can I say. I was going to stick this into a service which calls this at suspend, resume, shutdown and startup. Haven't worked out what to do for screen saver and for when remote buttons are pressed. [CODE]using System; using System.Collections.Generic; using System.Text; using System.IO.Ports; namespace TVControlApp { public class TVControl { public static string cmdPowerOff = "ka 01 00" + (char)0x0D; public static string cmdPowerOn = "ka 01 01" + (char)0x0D; public static string cmdPowerStatus = "ka 01 FF" + (char)0x0D; public static string cmdInputRGB = "xb 01 50" + (char)0x0D; public static string cmdInputTV = "xb 01 10" + (char)0x0D; public static string cmdInputStatus = "xb 01 FF" + (char)0x0D; public static string cmdVolumeLevel = "kf 01 FF" + (char)0x0D; public static string cmdVolumeUp = "mc 01 02" + (char)0x0D; public static string cmdVolumeDown = "mc 01 03" + (char)0x0D; public TVControl() { //create an Serial Port object } public string Do(string cmd) { return SendCommand(cmd); } private String SendCommand(String Command) { SerialPort sp = new SerialPort(); sp.ReadTimeout = 500; string ReturnCommand = ""; try { sp.Open(); for (int i = 1; i <= 5; i++) { //write line to serial port sp.WriteLine(Command); try { ReturnCommand = sp.ReadLine(); } catch { } if (ReturnCommand != "") break; } } catch (System.Exception ex) { ReturnCommand = ex.Message; } try { sp.Close(); } catch { } return ReturnCommand; } } }[/CODE] [/QUOTE]
