Hi, Perhaps the script below works…
# set up the baud rate and no parity stty -F /dev/ttyUSB0 9600 -parenb # listen on TCP port 8001 and forward all traffic to the serial port while [ 1 ] ; do nc -l $(hostname -i) 8001 </dev/ttyUSB0 >/dev/ttyUSB0; echo reconnecting ...; done Then intercept all network traffic from port 8001 (tcpdump?) Best wishes. From: Richard Shaw <hobbes1...@gmail.com> Sent: 19 July 2020 22:23 To: Development discussions related to Fedora <devel@lists.fedoraproject.org> Subject: Serial port sniffing? I would like to monitor serial port communications read only, but I haven't found a tool that makes that easy in the Fedora repos. Anyone have suggestions? Thanks, Richard
