RE: Serial port sniffing?

[Ronaldo Mercado]

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.

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
