29 Description: DAS-08 compatible boards
30 Author: Warren Jasper, ds, Frank Hess
31 Devices: [Keithley Metrabyte] DAS08 (isa-das08), [ComputerBoards] DAS08 (isa-das08),
32 DAS08-PGM (das08-pgm),
33 DAS08-PGH (das08-pgh), DAS08-PGL (das08-pgl), DAS08-AOH (das08-aoh),
34 DAS08-AOL (das08-aol), DAS08-AOM (das08-aom), DAS08/JR-AO (das08/jr-ao),
35 DAS08/JR-16-AO (das08jr-16-ao), PCI-DAS08 (das08),
36 PC104-DAS08 (pc104-das08), DAS08/JR/16 (das08jr/16)
39 This is a rewrite of the das08 and das08jr drivers.
41 Options (for ISA cards):
44 Options (for pci-das08):
48 The das08 driver doesn't support asynchronous commands, since
49 the cheap das08 hardware doesn't really support them. The
50 comedi_rt_timer driver can be used to emulate commands for this
