我做了一个小程序，女巫可以通过串口发送和接收。我的问题是，当我发送命令 ex: "netcfg" 我得到这个回声：
在空格处显示 UTF8 代码 08。如果转换为 java 脚本，则会显示：\b 但输出必须是：netcfg，而不是：n ne net netc netcf netcfg
所以我想要的输出是这样的：“sds://>netcfg”然后换行。
我可以看到设备理解我的命令，但这看起来不太好，所以请帮助我。
我的代码现在很乱，但无论如何：

public Form1()
{
InitializeComponent();
if (!mySerialPort.IsOpen)
{
mySerialPort.Open();
txtTerminal.Text = "The port is now open";
}
else
{
txtTerminal.Text = "The port is in use";
}
}
private void mySerialPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
_TerminalString = mySerialPort.ReadExisting();
Invoke(new EventHandler(displayText));
}
private void displayText(object o, EventArgs e)
{
byte[] str2 = Encoding.ASCII.GetBytes(txtSend.Text);
var testList = new List<byte>(str2);
testList.Add(0x0D);
byte[] str3 = testList.ToArray();
mySerialPort.Write(str3, 0, str3.Length);
txtTerminal.AppendText(_TerminalString);
