serial

Provides methods for working with serial ports.

getBuffer
Return data buffer.
Returns:
CircularStringBuffer - Data buffer.
list
Returns list of available ports.
See https://github.com/EmergingTechnologyAdvisors/node-serialport#module_serialport--SerialPort.list for details about the structure of returned values.
Returns:
Array.<Object> - Array of port descriptions.
open
Opens a serial port.
Data from the opened port will be automatically read line by line into a circular buffer. Once the buffer reaches it's maximum capacity specified by bufferSize argument, eldest entries are evicted to make room for new data.
 Serial port properties with default values:
{
  baudRate: 9600,
  dataBits: 8,        // Must be one of: 8, 7, 6, or 5.
  stopBits: 1,        // Must be one of: 1 or 2.
  parity: 'none'      // Must be one of: 'none', 'even', 'mark', 'odd', 'space'.
  rtscts: false,
  xon: false,
  xoff: false,
  xany: false
}
Parameters:
Name
Type
Description
port
String
Path to serial port. E.g. '/dev/tty-usbserial1', 'COM5', etc.
opts
Object
Port properties.
bufferSize
Number
optional Size of the input data buffer. Default is 65536 bytes.
Returns:
SerialPort - SerialPort object.
waitForText
Waits for text to appear in the input data buffer.
Text pattern can be any of the supported string matching patterns(on the top of page).
Parameters:
Name
Type
Description
pattern
String
Text pattern.
timeout
