串行端口还是USB端口？

[英]serialport or USB port?

原文 2010-06-15 04:14:39 1 1 c#/ usb/ sms

i am using this code:: 我正在使用此代码：：

c# serialport question C＃串口问题

to check what port my USB phone is connected to. 检查我的USB电话连接到哪个端口。

supposedly USB would be a virtual com, but this seems to be incorrect 据说USB将是一个虚拟com，但这似乎是不正确的

i used the above code to detect where my phone is and the output is just garbage. 我使用上面的代码来检测我的手机在哪里，输出只是垃圾。

is there a way for me to get c# to speak to my usb port so that i can speak to the gsm phone connected to it? 有没有办法让C＃与USB端口通话，以便我可以与与其连接的GSM电话通话？

Virtual COM doesn't mean it's supposed to answer to "ATI". 虚拟COM并不意味着它应该回答“ ATI”。 ATI is hayes modem command, not supported by every device. ATI是hayes modem命令，并非所有设备都支持。

SerialPort.ReadLine（）不从Arduino发送的USB COM端口读取数据 - SerialPort.ReadLine() does not read data from USB COM port sent by Arduino

如果正在使用的 USB COM 端口已被移除，SerialPort.Close() 会冻结应用程序 - SerialPort.Close() freezes application if the USB COM Port in use has been removed

"从 USB 串行端口读取时，SerialPort.BaseStream.ReadAsync 丢弃或加扰字节" - SerialPort.BaseStream.ReadAsync drops or scrambles bytes when reading from a USB Serial Port

C＃SerialPort侦听端口 - C# SerialPort Listening Port

C＃串行端口或USB HID连接？ - C# Serialport or USB HID connection?

SerialPort 实际上并没有打开 VirtualCOM 端口 - SerialPort doesn't actually open the VirtualCOM port

SerialPort.GetPortNames（）返回错误的端口名称 - SerialPort.GetPortNames() returns incorrect port names

串行端口“SerialPort.GetPortNames”没有读取任何内容 - Serial Port "SerialPort.GetPortNames" not reading anything

USB端口电流值 - USB port current value

SerialPort port.open“端口'COM2'不存在。” - SerialPort port.open “The port 'COM2' does not exist.”
