The Device Kit: Constants and Defined Types

This section lists all the constants and types defined for the BJoystick, BSerialPort, BDigitalPort, BA2D, and BD2A classes--though, in fact, only the BSerialPort class relies on any defined constants or types. Everything listed here is explained more fully in the descriptions of the member functions of that class.

Constants

data_bits Constants

Declared in: <device/SerialPort.h>

Enumerated constant
B_DATA_BITS_7
B_DATA_BITS_8

These constants name the possible number of data bits in a serial unit.

See also: BSerialPort::SetDataBits()

data_rate Constants

Declared in: <device/SerialPort.h>

Enumerated constant	Enumerated constant
B_0_BPS	B_1800_BPS
B_50_BPS	B_2400_BPS
B_75_BPS	B_4800_BPS
B_110_BPS	B_9600_BPS
B_134_BPS	B_19200_BPS
B_150_BPS	B_31250_BPS
B_200_BPS	B_38400_BPS
B_300_BPS	B_57600_BPS
B_600_BPS	B_115200_BPS
B_1200_BPS	B_230400_BPS

These constants give the possible rates--in bits per second (bps)--at which data can be transmitted and received over a serial connection. Not all rates are compatible with all serial ports.

See also: BSerialPort::SetDataRate()

Flow Control Constants

Declared in: <device/SerialPort.h>

Enumerated constant
B_SOFTWARE_CONTROL
B_HARDWARE_CONTROL

These constants form a mask that records the method(s) of flow control the serial port driver should use.

See also: BSerialPort::SetFlowControl()

parity_mode Constants

Declared in: <device/SerialPort.h>

Enumerated constant
B_NO_PARITY
B_ODD_PARITY
B_EVEN_PARITY

These constants list the possibilities for parity when transmitting data over a serial connection.

See also: BSerialPort::SetDataBits()

stop_bits Constants

Declared in: <device/SerialPort.h>

Enumerated constant
B_STOP_BITS_1
B_STOP_BITS_2

These constants name the possible number of stop bits in a serial unit.

See also: BSerialPort::SetDataBits()

Defined Types

data_bits

Declared in: <device/SerialPort.h>

      typedef enum { . . . } data_bits 

This type is used to set and return the number of data bits in a serial unit.

See also: "data_bits Constants" above, BSerialPort::SetDataBits()

data_rate

Declared in: <device/SerialPort.h>

      typedef enum { . . . } data_rate 

This type is used to set and return the rate at which data is sent and received through a serial connection.

See also: "data_rate Constants" above, BSerialPort::SetDataRate()

parity_mode

Declared in: <device/SerialPort.h>

      typedef enum { . . . } parity_mode 

This type is used to set and return the type of parity that should be used when sending and receiving data.

See also: "parity_mode Constants" above, BSerialPort::SetDataBits()

stop_bits

Declared in: <device/SerialPort.h>

      typedef enum { . . . } stop_bits 

This type is used to set and return the number of stop bits in a serial unit.

See also: "stop_bits Constants" above, BSerialPort::SetDataBits()
