The writable
read-only property of the SerialPort
interface returns a WritableStream
for sending data to the device connected to the port. Chunks written to this stream must be instances of ArrayBuffer
, TypedArray
, or DataView
. This property is non-null as long as the port is open and has not encountered a fatal error.
