  27 Description: National Instruments PCMCIA DAQCard-700 DIO only
  28 Author: Fred Brooks <nsaspook@nsaspook.com>,
  29   based on ni_daq_dio24 by Daniel Vecino Castel <dvecino@able.es>
  30 Devices: [National Instruments] PCMCIA DAQ-Card-700 (ni_daq_700)
  31 Status: works
  32 Updated: Thu, 21 Feb 2008 12:07:20 +0000
  33
  34 The daqcard-700 appears in Comedi as a single digital I/O subdevice with
  35 16 channels.  The channel 0 corresponds to the daqcard-700's output
  36 port, bit 0; channel 8 corresponds to the input port, bit 0.
  37
  38 Direction configuration: channels 0-7 output, 8-15 input (8225 device
  39 emu as port A output, port B input, port C N/A).
  40
  41 IRQ is assigned but not used.
