Inputs Over a Com Port

Question

Hi i am currently trying to make an application to access a device over a COM port but have run into some trouble to access the soft ware on the device the application needs to hit enter twice then input a password followed by hitting enter again this is the code i have so far. any suggestions would be appreciated thanks in advance.` static void Main()
{

        Port = new SerialPort();  
        Port.PortName = "COM21";  
        Port.BaudRate = 1200;  
        Port.DataBits = 8;  
        Port.Parity = Parity.None;  
        Port.StopBits = StopBits.One;  
        buoyPort.Open();  


        Port.Write(new byte[] { 13 }, 0, 1);  
        Thread.Sleep(250);  
        Port.Write(new byte[] { 13 }, 0, 1);  
        Thread.Sleep(250);  
        Port.Write("111047");  
        Thread.Sleep(250);  
        Port.Write(new byte[] { 13 }, 0, 1);`  

Answer 1

Hi just thought i would share that i just found the solution to this problem what was happening is the information was being sent to fast and the firmware on the device wasn't reading it in time so i ended up splitting the 111047 into separate parts and had spaced out by about half a second. Port.Write(new byte[] { 13 }, 0, 1); Thread.Sleep(250); Port.Write(new byte[] { 13 }, 0, 1); Thread.Sleep(500); Port.Write("1"); Thread.Sleep(500); Port.Write("1"); Thread.Sleep(500); Port.Write("1"); Thread.Sleep(500); Port.Write("0"); Thread.Sleep(500); Port.Write("4"); Thread.Sleep(500); Port.Write("7"); Thread.Sleep(500); Port.Write(new byte[] { 13 }, 0, 1);
