comedirecord is an oscilloscope program to record data from a COMEDI-compatible device. Its philosophy is to save the data in its original unfiltered form but allow comfortable viewing of the data during an experiment. One can acquire data from multiple DAQ boards simultaneously, and also append data via an incoming TCP port, which could be a telnet connection into comedirecord or data from another program. Low-pass, high-pass, and notch filters can be switched on for each channel. A DC filter can be switched on, which is useful when observing small voltage changes at a high gain (for example, measuring small temperature changes). The output format is ASCII so that the data can be imported into GNUPLOT, scilab, or octave.
