27 # When fast-centronics is set to "true", handshaking between the
28 # driver and the peripheral is conducted by hardware. For some
29 # Centronics devices the hardware handshaking is too fast for the
30 # peripheral. To slow down the handshaking, fast-centronics must
31 # be set to "false". By default fast-centronics is set to "false".
33 fast-centronics="false";
36 # When fast-1284-compatible is set to "true", IEEE 1284 compliant
37 # devices operating in Compatibility mode will have the parallel port
38 # handshaking controlled by the hardware. When it is set to "false"
39 # handshaking is PIO controlled by the driver. By default
40 # fast-1284-compatible is set "true".

45 # Some Centronics devices require the Init signal to be toggled upon
46 # power-up. The application should do this directly with ioctl(2) interface
47 # as specified in ecpp(4D). As an alternative to using the API, the driver
48 # may be configured to toggle the nInit signal upon every time the device
49 # is opened. If centronics-init-seq is set to "true" the Init signal
50 # will be toggled when the device is opened. The default is "false".

56 # ecpp will re-examine the device every centronics-retry milliseconds.

63 # The driver waits for centronics-wait-for-busy microseconds for a
