Serial

Golang package for serial port

A Go package that allow you to read and write from the serial port.

This is a forked repo written by @tarm.

Usage

package main
 
import (
	"time"
	"github.com/argandas/serial"
)

func main() {
    sp := serial.New()
    err := sp.Open("COM1", 9600)
    if err != nil {
        panic(err)
    }
    defer sp.Close()
    sp.Println("AT")
    sp.WaitForRegexTimeout("OK.*", time.Second * 10)
}

NonBlocking Mode

By default the returned serial port reads in blocking mode. Which means Read() will block until at least one byte is returned. If that's not what you want, specify a positive ReadTimeout and the Read() will timeout returning 0 bytes if no bytes are read. Please note that this is the total timeout the read operation will wait and not the interval timeout between two bytes.

	sp := serial.New()
    err := sp.Open("COM1", 9600, time.Second * 5)
