-----Ruby/SerialPort----- -- Description -- Ruby/SerialPort is a Ruby library that provides a class for using RS-232 serial ports. This class also contains low-level functions to check and set the current state of the signals on the line. The native Windows version of this library supports Microsoft's Visual C++ and Borland's C++ compilers. -- Installation -- $ ruby extconf.rb $ make $ make install -- Testing -- * test/miniterm.rb Ruby's copy of miniterm.c ! -- API -- **** Class SerialPort, Parent IO **** ** Class constants ** VERSION -> aString (this release is "0.6") NONE, HARD, SOFT, SPACE, MARK, EVEN, ODD -> anInteger ** Class methods ** * new(port_num [, modem_parameters]) -> aSerialPort * open(port_num [, modem_parameters]) -> aSerialPort * open(port_num [, modem_parameters]) {|aSerialPort| block} -> nil port_num -> anInteger: port number, 0 for first port which is "/dev/ttyS0" on GNU/Linux and "COM1" on Windows, or aString: file name of the device (example: "/dev/ttyS2") Optional modem_parameters: baudrate -> anInteger: from 50 to 256000, depends on platform. databits -> anInteger: from 5 to 8 (4 is allowed on Windows) stopbits -> anInteger: 1 or 2 (1.5 is not supported) parity -> anInteger: SerialPort::NONE, SerialPort::EVEN, SerialPort::ODD, SerialPort::MARK, SerialPort::SPACE (MARK and SPACE are not supported on Posix) Raise an argError on bad argument. SerialPort.new and SerialPort.open without a block return an instance of SerialPort. SerialPort.open with a block passes a SerialPort to the block and closes it when the block exits (like File.open). ** Instance methods ** * modem_params() -> aHash * modem_params=(aHash) -> self * get_modem_params() -> aHash * set_modem_params(aHash) -> self * set_modem_params(baudrate [, databits [, stopbits [, parity]]]) Get and set the modem parameters. Hash keys are "baud", "data_bits", "stop_bits", and "parity" (see above). Parameters not present in the hash or set to nil remain unchanged. Default parameter values for the set_modem_params method are: databits = 8, stopbits = 1, parity = (databits == 8 ? SerialPort::NONE : SerialPort::EVEN). * baud() -> anInteger * baud=(anInteger) -> self * data_bits() -> 4, 5, 6, 7, or 8 * data_bits=(anInteger) -> self * stop_bits() -> 1 or 2 * stop_bits=(anInteger) -> self * parity() -> anInteger: SerialPort::NONE, SerialPort::EVEN, SerialPort::ODD, SerialPort::MARK, or SerialPort::SPACE * parity=(anInteger) -> self Get and set the corresponding modem parameter. * flow_control() -> anInteger * flow_control=(anInteger) -> self Get and set the flow control: SerialPort::NONE, SerialPort::HARD, SerialPort::SOFT, or (SerialPort::HARD | SerialPort::SOFT). Note: SerialPort::HARD mode is not supported on all platforms. SerialPort::HARD uses RTS/CTS handshaking; DSR/DTR is not supported. * read_timeout() -> anInteger * read_timeout=(anInteger) -> self * write_timeout() -> anInteger * write_timeout=(anInteger) -> self Get and set timeout values (in milliseconds) for reading and writing. A negative read timeout will return all the available data without waiting, a zero read timeout will not return until at least one byte is available, and a positive read timeout returns when the requested number of bytes is available or the interval between the arrival of two bytes exceeds the timeout value. Note: Read timeouts don't mix well with multi-threading. Note: Under Posix, write timeouts are not implemented. * break(time) -> nil Send a break for the given time. time -> anInteger: tenths-of-a-second for the break. Note: Under Posix, this value is very approximate. * signals() -> anHash Return a hash with the state of each line status bit. Keys are "rts", "dtr", "cts", "dsr", "dcd", and "ri". Note: Under Windows, the rts and dtr values are not included. * rts() * dtr() * cts() * dsr() * dcd() * ri() -> 0 or 1 * rts=(0 or 1) * dtr=(0 or 1) -> self Get and set the corresponding line status bit. Note: Under Windows, rts() and dtr() are not implemented. -- License -- GPL Guillaume Pierronnet <moumar@netcourrier.com> Alan Stern <stern@rowland.harvard.edu>
