+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.
