Member Function Documentation

int LinuxSerialPort::Open (  unsigned  port  )  [virtual]

Open port for communications over a specified port number. Parameters: port  Port number. Returns: Zero if successful, or a negative error value if failed. Implements SerialPort. Definition at line 94 of file serial_port.cpp.

int LinuxSerialPort::Initialise (  unsigned  baud  )  [virtual]

Initialise port. Parameters: baud  Baud rate for port. Returns: Zero if successful, or a negative error value if failed. Precondition: Open() must have been called. Implements SerialPort. Definition at line 139 of file serial_port.cpp.

int LinuxSerialPort::Out (  const uint8_t *  data, size_t  size, unsigned  timeout )  [virtual]

Transmit data. This function does not wait if only some of data could be transmitted, instead it returns immediately. Parameters: data  Pointer to data to be transmitted. size  Size of data. timeout  Time in milliseconds to wait if output is not ready. Returns: Number of bytes transmitted or negative error value if failed. Precondition: Initialise() must have been called. Implements SerialPort. Definition at line 172 of file serial_port.cpp.

int LinuxSerialPort::In (  uint8_t *  data, size_t  maxSize, unsigned  timeout )  [virtual]

Receive data. Parameters: [out]  data  Pointer to buffer to hold received data. maxSize  Size of data. timeout  Time in milliseconds to wait if no data available. Returns: Number of bytes received or negative error value if failed. Precondition: Initialise() must have been called. Implements SerialPort. Definition at line 216 of file serial_port.cpp.

void LinuxSerialPort::Close (   )  [virtual]

Close port. Port must not be used again until Open() has been called. Implements SerialPort. Definition at line 260 of file serial_port.cpp.

int LinuxSerialPort::Error (  int  defaultError = ErrorUnspecified  )  [private]

Process an error. Parameters: defaultError  The default error value to return. Returns: An error value from Errors Definition at line 84 of file serial_port.cpp.
