Due to the ruby-serialport project provided by RubyForge.org apparently
|
|
being unmaintained, this is a MSF-specific fork of that project. This
|
|
version has been modified by both MSF developers as well as by applying
|
|
a patch found submitted to the RubyForge project but never included in
|
|
the distribution provided there. The versioning scheme has been updated
|
|
from the format X.y, to X.Y.z-msf. The text accompanying the applied
|
|
patch can be found below.
|
|
|
|
Please see the README.orig file for the original project's README, which
|
|
includes buid and install instructions as well as documentation of the
|
|
SerialPort Class API.

[#878] Six new methods (implemented for the posix flavor only) for the
|
|
SerialPort class
|
|
|
|
I had to use the SerialPort class to communicate chunks of binary data
|
|
through the serial port, and i needed to set some of the low-level
|
|
flags onto the serial fd using fcntl() and tcsetattr(), so I implemented
|
|
some nifty methods and added them to the class.
|
|
|
|
The six new methods are:
|
|
|
|
.nonblock= and .nonblock() -> Manipulate the O_NONBLOCK descriptor flag
|
|
.input_type= and .input_type() -> Manipulate the ICANON/RAW input flags
|
|
.output_type= and .output_type() -> Manipulate the OPOST/RAW output flags
|
|
|
|
Also two new constants were added:
|
|
|
|
SerialPort::PROCESSED -> Identifies the CANONICAL/PROCESSED I/O
|
|
SerialPort::RAW -> Identifies the RAW/RAW I/O
|
|
|
|
Example usage:
|
|
|
|
def open_port
|
|
ret = SerialPort.new @device
|
|
|
|
ret.baud = @port_baud
|
|
ret.data_bits = @port_data_bits
|
|
ret.stop_bits = @port_stop_bits
|
|
ret.parity = SerialPort::NONE
|
|
ret.flow_control = SerialPort::HARD
|
|
ret.input_type = SerialPort::RAW
|
|
ret.output_type = SerialPort::RAW
|
|
ret.read_timeout = -1
|
|
ret.nonblock = false
|
|
ret.dtr = 1
|
|
|
|
ret
|
|
end
|
|
|
|
This was the best setup for modem communications I could achieve, for
|
|
binary and string I/O, in a multithreaded application. Obviously YMMV.
