[UWP] Windows 10应用程序 - CustomSerialDeviceAccess示例无法打开COM1

问题描述：

尝试使用官方串口示例（CustomSerialDeviceAccess）打开COM1时，出现以下错误：

When attempting to open COM1 using the official serial port sample (CustomSerialDeviceAccess), I get the following error:

"系统找不到指定的文件。（来自HRESULT的异常：0x80070002）<

"The system cannot find the file specified. (Exception from HRESULT: 0x80070002)"

从串行设备选择器返回的ID：@" \\？\ ACPI＃PNP0501＃5& 36cbe709& 0＃{ 86e0d1e0-8089-11d0-9ce4-08003e301f73}"

Id as returned from the serial device selector: @"\\?\ACPI#PNP0501#5&36cbe709&0#{86e0d1e0-8089-11d0-9ce4-08003e301f73}"

Driver Details

类：端口

Class Guid为{4d36e978-e325-11ce-bfc1-08002be10318}

Class Guid as {4d36e978-e325-11ce-bfc1-08002be10318}

Inf名称：msports.inf

Inf name: msports.inf

使用RealTerm（Win32终端程序）我可以打开并与COM1通信就好了。

Using RealTerm (a Win32 terminal program) I can open and communicate with COM1 just fine.

任何想法？

解决方法的想法？

谢谢。

您是否从这里下载样本（https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/ CustomSerialDeviceAccess）？

Hi lil'sprout,

>>"When attempting to open COM1 using the official serial port sample (CustomSerialDeviceAccess),"
Do you download the sample from here(https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/CustomSerialDeviceAccess)?

>> 我收到以下错误："

>>I get the following error:"The system cannot find the file specified. (Exception from HRESULT: 0x80070002)"

异常在哪里被抛出？
