通过 MSComm1 发送 ctrl-E

Question

如何通过串口 MSComm1 发送 ctrl-E ？ 它应该继续传递 ctrl-E....就像 for 循环或 do while 循环..这是我的代码：

MSComm1.CommPort = Convert.ToInt16(Settings.Default.PortName); SendKeys.Send("^(e)");
MSComm1.Settings = Settings.Default.BaudRate.ToString().Trim() + "," + Settings.Default.Parity.Substring(0, 1).ToString().Trim() + "," + Settings.Default .DataBits.ToString().Trim() + "," + Settings.Default.StopBits.ToString().Trim();
MSComm1.PortOpen = true;
MSComm1.InputLen = 0;
MSComm1.InputMode = MSCommLib.InputModeConstants.comInputModeText;
if (Settings.Default.FlowControl == "Xon/Xoff")
{
MSComm1.Handshaking = MSCommLib.HandshakeConstants.comXOnXoff;
}
else if (Settings.Default.FlowControl == "None")
{
MSComm1.Handshaking = MSCommLib.HandshakeConstants.comNone;
}
else if (Settings.Default.FlowControl == "RTS")
{
MSComm1.Handshaking = MSCommLib.HandshakeConstants.comRTS;
}
else if (Settings.Default.FlowControl == "RTSXon/Xoff")
{
MSComm1.Handshaking = MSCommLib.HandshakeConstants.comRTSXOnXOff; }

Answer 1

Control-E 是 5 的键盘快捷键，因此：（

serial.Write(new byte[]{ 5 }, 0, 1);

假设串行是 System.IO.Ports.SerialPort 的实例。）

Answer 2

使用 C# 进行串行端口通信，来自 此处：

private static void SendSampleData() {
  // Instantiate the communications
  // port with some basic settings
  SerialPort port = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);

  // Open the port for communications
  port.Open();

  // Write a string
  port.Write("Hello World");

  // Write a set of bytes
  port.Write(new byte[] {0x0A, 0xE2, 0xFF}, 0, 3);

  // Close the port
  port.Close(); 
}

现在您只需以某种方式对 Ctrl+E 进行编码即可。
