I have NMEA text traffic coming in a USB port which I would like to capture & massage. I can view this traffic through cu(1). I realize script(1) can capture serial output, but I don't want to spool all this data to disk; I would rather intercept the traffic to compute various parameters & throw it away. Is there a way I can split off this traffic for analysis in Perl?

Thanks for any candor shared.
