47 | * The following table configures the console drivers used in this BSP. |
---|
48 | * |
---|
49 | * The first entry which, when probed, is available, will be named /dev/console, |
---|
50 | * all others being given the name indicated. |
---|
51 | * |
---|
52 | * Each field is interpreted thus: |
---|
53 | * |
---|
54 | * sDeviceName This is the name of the device. |
---|
55 | * pDeviceFns This is a pointer to the set of driver routines to use. |
---|
56 | * pDeviceFlow This is a pointer to the set of flow control routines to |
---|
57 | * use. Serial device drivers will typically supply RTSCTS |
---|
58 | * and DTRCTS handshake routines for DCE to DCE communication, |
---|
59 | * however for DCE to DTE communication, no such routines |
---|
60 | * should be necessary as RTS will be driven automatically |
---|
61 | * when the transmitter is active. |
---|
62 | * ulMargin The high water mark in the input buffer is set to the buffer |
---|
63 | * size less ulMargin. Once this level is reached, the driver's |
---|
64 | * flow control routine used to stop the remote transmitter will |
---|
65 | * be called. This figure should be greater than or equal to |
---|
66 | * the number of stages of FIFO between the transmitter and |
---|
67 | * receiver. |
---|
68 | * ulHysteresis After the high water mark specified by ulMargin has been |
---|
69 | * reached, the driver's routine to re-start the remote |
---|
70 | * transmitter will be called once the level in the input |
---|
71 | * buffer has fallen by ulHysteresis bytes. |
---|
72 | * pDeviceParams This contains either device specific data or a pointer to a |
---|
73 | * device specific structure containing additional information |
---|
74 | * not provided in this table. |
---|
75 | * ulCtrlPort1 This is the primary control port number for the device. This |
---|
76 | * may be used to specify different instances of the same device |
---|
77 | * type. |
---|
78 | * ulCtrlPort2 This is the secondary control port number, of use when a given |
---|
79 | * device has more than one available channel. |
---|
80 | * ulDataPort This is the port number for the data port of the device |
---|
81 | * ulIntVector This encodes the interrupt vector of the device. |
