Configuration Table Use
=======================
sDeviceName
The name of this device.
deviceType
This field must be SERIAL_Z85C30.
pDeviceFns
The device interface control table. This may be:
+ z85c30_fns for interrupt driven IO
+ z85c30_fns_polled for polled IO
deviceProbe
This is the address of the routine which probes to see if the device
is present.
pDeviceFlow
This field is set to one of the following values:
+ NULL for no hardware flow control
+ z85c30_flow_RTSCTS for RTS/CTS based flow control
+ z85c30_flow_DTRCTS for DTR/CTS based flow control
ulMargin
This is currently unused.
ulHysteresis
This is currently unused.
pDeviceParams
This is set to the default settings.
ulCtrlPort1
This field is the address of the control register for this port.
ulCtrlPort2
This field is the address of the control register for chip.
ulDataPort
This field is the address of the data register for this port.
getRegister
setRegister
These follow standard conventions.
getData
