SerialPort class abstract

Serial port.

Provides means to:

obtaining a list of serial ports on the system
opening, closing and getting information about ports
signals, modem control lines, breaks, etc.
low-level reading and writing data, and buffer management

Note: The port must be disposed using dispose() when done.

Error handling

Serial Port for Dart throws SerialPortError in case something goes wrong under the hood in libserialport and it returns an error code:

final port = SerialPort(...);
  port.write(...);
try {
} on SerialPortError catch (e) {
  print(SerialPort.lastError);
}

The error message is that provided by the OS, using the current language settings. The library does not define its own error codes or messages to accompany other return codes.

Methods

close() → bool: Closes the serial port.
dispose() → void: Releases all resources associated with the serial port.
