### The "STTY" package

This package provides simplified way to invoke **stty** utility to perform some
tasks by means of it. For now the only a few number of functions are implemented:
- set tty baudrate 
- check tty baudrate 
- test if selected baudrate is available for some tty
- test if a given file is a tty

-------------

### Usage
1. Download the package by **go get** command:
```shell
go get code.foilhatguy.casa/pub/stty
```

2. Import package to your golang code:
```go
import (
	"code.foilhatguy.casa/pub/stty"
)
```

3. Test if some file is a tty:
```go
    err := stty.ValidateTtyFile("/dev/ttyUSB0")
```

4. Use stty object to perform some tasks. For instance, test if baudrate of 9600
is available at **/dev/ttyUSB0**: 
```go
    err := stty.CMD().TestBaudRate("/dev/ttyUSB0", 9600)
```

If **stty** is not available stty, all methods of object returned by CMD() function 
will return ERR_TTY_MISSING error.
