Serial Protocols Sertrace Utility
The command line sertrace utility offers the ability to trace the activity of serial ports
in real time. A port range may be specified to limit the output to specific ports. The
level of traffic to trace and the type of decoding may be specified. The tool may also
be used to force the port to transmit an output test message. The following is an
example of sertrace use:
RuggedRouter:~# sertrace -h
Trace Serial Protocol Server Activity
Usage: sertrace [-dtr] [-p portrange]
serserver -d protocol decode
serserver -t tcp level events
serserver -r raw packet display
serserver -p ports to capture (e.g 1,3,6-7)
serserver -s ports to send a test message out on (when 's' + Enter keys are pressed)
In the absence of parameters, all decoding on all ports is provided.
