For more information about available methods, refer to the roSerialPort entry.
If possible, use @brightsign/serialport with the Node Package serialport instead of BSSerialPort. A basic reference implementation can be found in this GitHub repository.
Object Creation
BSSerialPort(in unsigned long port);
Methods
void SetBaudRate(in unsigned long baudRate) raises(DOMException)
...
Shuts down the instance, preventing it from further consuming resources. If this method is not called, garbage collection determines when the instance will be destroyed.
Events
The following events are available via the BSSerialPort object. Each event can receive a SerialPortEvent event.
onserialbyte
onserialline
SerialPortEvent – Attributes
For the onserialbyte event:
...
readonly attribute DOMString sdata

function serialOut()

console.log("*** serialOut **");
// '2' is the first externally connected USB port on Cheetah
var serial_out = new BSSerialPort(2);
serial_out.SetBaudRate(115200);
serial_out.SetDataBits(8);
serial_out.SetStopBits(1);
serial_out.SetParity("none");
serial_out.SetEcho(true);
serial_out.SetGenerateByteEvent(true);
serial_out.SetGenerateLineEvent(true);
serial_out.onserialbyte = function(e){
console.log('### onserialbyte: ' + e.sbyte);
}
serial_out.onserialline = function(e){
console.log('### onserialline: ' + e.sdata);
}
serial_out.SendByte(89);
serial_out.SendByte(90);
serial_out.SendByte(91);
serial_out.SendBytes('Hello World!');
serial_out.SendBytes(String.fromCharCode(64, 27, 66, 67))
