Can be useful for testing serial parsers with real data.

the problem is the pacing of the data, it would be better to have a small py script that reads a file at a given rate and sends to a tcp port

[peterbarker]

@tridge true enough. What I'd like is to finish up my write-pcap-file and feed that into such a script.

The protocol I was working with here was a time-independent capture which provided useful exercise for the parser.

It's nothing that can't be done with socat and a tcp port - it's just more hassle.

It also occurs to me that file could probably be a pipe, 'though....

Kill this or keep it?

I needs a NMEA capture as input tonight, and did this:

it assumes a line based protocol. It allowed me to find the issue for this report v quickly:

No appetite for this in master.
