C# PCI Express Последовательный порт

Question

Я создал новую программу с C#, используя связь по последовательному порту. Программа работает без ошибок при общении с Digitus RS232 - USB Converter. Но он не подключает компьютер с модулем последовательного порта PCI Express. При подключении я получаю ошибку ввода-вывода. Можете ли вы помочь мне в этой ошибке?

Answer 1

Сведения об исключении;

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging ************** 
To enable just-in-time (JIT) debugging, the .config file for this 
application or computer (machine.config) must have the 
jitDebugging value set in the system.windows.forms section. 
The application must also be compiled with debugging 
enabled. 

For example: 

<configuration> 
    <system.windows.forms jitDebugging="true" /> 
</configuration> 

When JIT debugging is enabled, any unhandled exception 
will be sent to the JIT debugger registered on the computer 
rather than be handled by this dialog box.
