Library Features

This java library provides a platform-independent way to access standard serial ports without requiring external libraries, native code, or any other tools. A general feature list includes:

• Platform-independent library deployment (automatically uses correct native library based on current architecture),
• Very lightweight and efficient implementation
• Enumerates all available serial ports on a machine
• Returns both a system port description and a friendly device description
• User-specifiable port descriptors including symbolic links
• Configurable ports according to baud rate, data bits, stop bits, and parity
• Configurable port timeouts (blocking and non-blocking) for both reading and writing
• Configurable flow control parameters for the serial port (CTS, RTS/CTS, DSR, DTR/DSR, XOn/XOff)
• Direct access to control lines including DTR and RTS
• Ability to read and write raw data bytes directly to the serial port
• Ability to read and write byte streams via Java's InputStream and OutputStream
• Event-based reading and writing capabilities via callbacks
• Callback notification when:
  • New data is available for reading
  • All data has been successfully written
  • A serial device has become disconnected
  • A complete fixed-length data packet has arrived
  • A delimited string-based message has been received
  • Modem control lines have changed state
  • Communication errors have been encountered
