This latest patch changes the interface to three functions: comedi_scxi_open comedi_scxi_close comedi_scxi_readwrite With these three functions one can properly interface to all SCXI devices. If you like the latest patch (3/23/04 07:14), please apply and close this bug. Next up will be adding some generic analog and digital IO functions.
