A Transform stream that emits buffered data when no new bytes have been received for a configurable interval. Useful for protocols whose frames are delimited by silence rather than a byte sequence (Modbus RTU, ASCII commands without trailing newline, etc.).

npm install @serialpilot/parser-inter-byte-timeout

Usage

const { SerialPilot, InterByteTimeoutParser } = require('serialpilot')

const port = new SerialPilot({ path: '/dev/ttyUSB0', baudRate: 9600 })
const parser = port.pipe(new InterByteTimeoutParser({ interval: 30 }))
parser.on('data', console.log)

API

new InterByteTimeoutParser({ interval, maxBufferSize })

| Option | Type | Default | Description | | --------------- | ------ | ------- | ------------------------------------------------------------ | | interval | number | — | Required. Milliseconds of silence before emitting (>= 1). | | maxBufferSize | number | 65536 | Maximum bytes buffered before forcing emit. |
