Excellent port sniffer! Exactly what I needed for debugging the bootloader code for a microcontroller. The only thing that stumped me for a few minutes was that it defaulted to BSD mode, but once I actually read the documentation, it was all clear. Great tool! Thanks!
Very good. I propose though, you should add a flag to output ascii and utf strings without the hex equivalent, this will make sniffing such data much more readable. I used it to debug my project, so i'll add you to my aknowledgements
very good. but I want it to display what content I send. so I can know if I send the right content from my app. thank you.
I needed a different output (pure hex, single line space) and after changing just two lines of code I was there. The power of open source!
Unlike my previous poster indicated this program works well with Unix 98 ptys. Just use the -u parameter (or --unix98 instead).
