class SerialPortWrapper(port: SerialPort) : AbstractSerialPortWrapper

Serial port implementation based on the jSerialComm library.

Parameters

port

SerialPort object used for managing a serial port

SerialPortWrapper

constructor(port: SerialPort)

Properties

defaultReadTimeout

open override var defaultReadTimeout: Long

Timeout in milliseconds after which a read operation should abort.

defaultWriteTimeout

open override var defaultWriteTimeout: Long

Timeout in milliseconds after which a write operation should abort.

productId

open override var productId: Int

PID value of the serial port, or -1 if unavailable

vendorId

Functions

bytesAvailable

open override fun bytesAvailable(): Int

Checks how many bytes are available to be read from the serial port.

open override fun close()

Closes a connection to the serial port.

isOpen

open override fun isOpen(): Boolean

Checks if there is an open connection to the serial port.

open

open override fun open()

Opens a connection to the serial port.

read

open suspend override fun read(numBytes: Int): ByteArray

open suspend override fun read(numBytes: Int, timeout: Long): ByteArray

Reads the specified number of bytes from the port.

open override fun read(numBytes: Int, scope: CoroutineScope): Deferred<ByteArray>

open override fun read(numBytes: Int, timeout: Long, scope: CoroutineScope): Deferred<ByteArray>

Reads the specified number of bytes from the port in an asynchronous manner.

readBytes

open suspend override fun readBytes(buffer: ByteArray): Int

Reads data from the serial port until the provided buffer is filled.

setBaudRate

open override fun setBaudRate(rate: Int)

Sets the baud rate of the connection to the serial port.

setDefaultTimeouts

open override fun setDefaultTimeouts(readTimeout: Long, writeTimeout: Long)

Sets the values of the port read and write timeouts.

setTimeout

open override fun setTimeout()

Sets the timeout behavior of the underlying serial port library.

use

open suspend override fun <T> use(callback: suspend (ISerialPortWrapper) -> T): T

Opens a connection to the serial port and closes it automatically after the callback has completed.

write

open suspend override fun write(bytes: ByteArray): Int

open suspend override fun write(bytes: ByteArray, timeout: Long): Int

Writes the provided bytes to the serial port.

open override fun write(bytes: ByteArray, scope: CoroutineScope): Deferred<Int>

open override fun write(bytes: ByteArray, timeout: Long, scope: CoroutineScope): Deferred<Int>

Writes the provided bytes to the serial port in an asynchronous manner.

writeBytes

open suspend override fun writeBytes(buffer: ByteArray): Int

Writes the provided byte data to the serial port.
