Property	Type	Description
`baudRate`	`number`	Baud rate of the device
`bufferSize?`	`number`	Size of the read buffer
`dataBits?`	`8` \| `7`	Number of data bits per frame (either 7 or 8)
`endOfLineString`	`string`	The end of line characters
`flowControl?`	`FlowControlType`	Flow control (aka handshake) type
`parity?`	`ParityType`	Parity mode of the device
`parseValue?`	`boolean`	Whether or not the value should be parsed by splitting the reading into columns and getting the value from one of the columns.
`productIdFilter?`	`number`	Number identifying the device. You must provide the Vendor ID if you provide this.
`splitReadingOn?`	`string`	If parseValue is set to true, the reading will be split into columns with this string. Must be set if parseValue is set to true.
`stopBits?`	`1` \| `2`	Number of stop bits at the end of each frame (either 1 or 2)
`valueIndex?`	`number`	If parseValue is set to true, this is the index of the column for the value. Must be set if parseValue is set to true.
`vendorIdFilter?`	`number`	Number identifying the device's vendor
