Hi Sometimes you have some needs to sniff what is going on a serial port. For example when you are debugging a microcontroller serial bootloader or when you want to reverse engineer a serial protocol from/to a binary blob. So far I have taken the approach of using strace with relative good results, but I miss a nice gui like wireshark. On the usb subsystem they have the supernice usbmon that can be accessed with wireshark and is very helpful for debugging usb transaction (even the ones initiated on a kvm virtual machine....) So I want to build a better alternative to strace for serial port monitoring and of course I would really want it to get upstream. I am considering two options: ebpf solution, and pure C kernel infrastructure as usbmon. - I have not used ebpf/bcc before, but seems like a very powerful tool and probably can do the job with a reduced amount of work, but I wont have a gui as good as wireshark - ttymon seems like the natural approach, but after 3 minutes of google I have not found any previous attempt on this direction, so I am probably missing something (or I have lost my google skils). All this said, how do you feel about something like this? Any ideas/feedback before I spam the list with patches?
