# serial.nim

A library to work with serial ports using pure Nim.

## Installation

`serial` can be installed using Nimble:

```

nimble install serial

```

Or add the following to your .nimble file:

```

# Dependencies

requires "serial >= 1.0.0"

```

## Usage

There are some examples in the `examples` directory, showing reading from and writing to a serialport.

### Listing serial ports

```nim

import serial # Or: `import serial/utils`

for port in listSerialPorts():

  echo port

```

### Reading from/writing to a serial port (echoing data)

```nim

import serial # Or: `import serial/serialport`

let port = newSerialPort("COM1")

# use 9600bps, no parity, 8 data bits and 1 stop bit

port.open(9600, Parity.None, 8, StopBits.One)

# You can modify the baud rate, parity, databits, etc. after opening the port

port.baudRate = 2400

var receiveBuffer = newString(1024)

while true:

  let numReceived = port.read(receiveBuffer)

  discard port.write(receiveBuffer[0 ..< numReceived])

```

### Using the SerialStream

```nim

import serial # Or: `import serial/serialstream`

let port = newSerialStream("COM1", 9600, Parity.None, 8, StopBits.One, buffered=true)

while true:

  # Read a line from the serial port then write it back.

  port.writeLine(port.readLine())

```

## Features

- Basic port reading/writing for Windows/Posix

- Port setting control - baud rate, stop bits, databits, parity, handshaking

- Port listing to list available serial ports

    - Windows, using `SetupDiGetClassDevs`

    - Mac, using I/O Kit

    - Posix, by iterating possible device files

- High level `SerialPortStream` that complies with the `streams` API

- Async API using `asyncdispatch` for reading from and writing to a port
