在另一个应用程序正在使用它时嗅探串行端口 /dev/ttyS0

Question

My platform: Linux Kubuntu 14

I am currently working on a project in which my application is communicating with a process via rs232 connected to /dev/ttyS0 serial port.

Sometimes incoming messages aren't intercepted by my process so I decided to use a sniffing tool called jpnevulator.

From what I see, if I run my application together with the sniffing tool, some messages are intercepted by the sniffing tool and some by my application, but not both.

Is it not possible to listen via sniffing tool on a serial port while another application is using it?

Thanks

Thanks all for the helpful responses. As suggested in https://unix.stackexchange.com/questions...

I used interceptty to link a pseudo terminal to the serial port I am listening to and connected my application to the pseudo terminal and it worked.
