Driver: ni_daq_700
Description: National Instruments PCMCIA DAQCard-700 DIO only
Author: Fred Brooks <nsaspook@nsaspook.com>,
  based on ni_daq_dio24 by Daniel Vecino Castel <dvecino@able.es>
Devices: [National Instruments] PCMCIA DAQ-Card-700 (ni_daq_700)
Status: works
Updated: Thu, 21 Feb 2008 12:07:20 +0000

The daqcard-700 appears in Comedi as a single digital I/O subdevice with
16 channels.  The channel 0 corresponds to the daqcard-700's output
port, bit 0; channel 8 corresponds to the input port, bit 0.

Direction configuration: channels 0-7 output, 8-15 input (8225 device
emu as port A output, port B input, port C N/A).

IRQ is assigned but not used.
