A [serial](https://en.wikipedia.org/wiki/Serial_communication) library written in TypeScript for [Deno](https://deno.land) without any third party modules.
914

1015
This library provides an interface for the communication with serial devices and **doesn't use any third party modules**. It uses C++ functions which are included in a [dynamic link library](https://de.wikipedia.org/wiki/Dynamic_Link_Library) or [shared object](https://en.wikipedia.org/wiki/Library_(computing)#Shared_libraries). These functions are then loaded by deno to establish a serial connection and talk to the devices.

## Possible/Known issues
3742
- What happens if you open multiple connections from the same instance.
3843
- Every function returns the status code although it is previously checked.
3944
- What happens if you async read 2 times directly after each other.
4045

### Usage
43-
#### `class` Serial
47+
## Examples - How to use
48+
### Ports
49+
Get a list with all serial ports and their info that are currently available on your system.
50+
51+
`main.ts`
4452
```typescript
45-
/**
46-
* Create a new instance of a serial connection.
47-
*/
48-
new Serial()
49-
```
53+
import { Serial } from "./mod.ts";
5054

51-
<br>
55+
// create new instance of a serial object
56+
const serial = new Serial();
5257

53-
#### `getter property` Serial.isOpen
54-
```typescript
55-
/**
56-
* Get the current connection status of the serial connection.
57-
* @returns {boolean} Returns `true` if the serial connection is open, otherwise returns `false`
58-
*/
59-
get isOpen() : boolean
58+
// get all available ports
59+
const availablePorts = serial.getPortsInfo();
60+
61+
// console log the list
62+
console.log(availablePorts);

### Sending
76+
Send data to a serial device. For exampe to an [Arduino](https://www.arduino.cc/).
77+
78+
`main.ts`

70-
* @param {SerialOptions} serialOptions Additional options for the serial connection (`data bits`, `parity`, `stop bits`)
71-
* @returns {number} The status code
