Alamat Register2 paralel port:

Register Alamat
Data register (Base Address + 0) 0x378
Status register (Base Address + 1) 0x379
Control register (Base Address + 2) 0x37a

Sebelum memprogram Paralel port anda harus mendowload  file

inpout32.dll  kemudian simpan di direktory system di windows anda.

1. Buat Project baru

2. Drag and drop 2 tombol dan 2 text box

3. buat class baru  , beri nama LPT

membuat Form dan Class baru

//untuk class LPT isinya sbb:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace WindowsFormsApplication2
{
    class LPT
    {
        [DllImport("inpout32.dll", EntryPoint = "Out32")]
        public static extern void Output(int adress, int value);
        [DllImport("inpout32.dll", EntryPoint = "Inp32")]
        public static extern int Input(int adress);
    }
}

Untuk di form utama isi code nya spt ini:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnKirimKeLPT_Click(object sender, EventArgs e)
        {
            LPT.Output(0x378, Int32.Parse(txtdataOut.Text));
        }

        private void btnBacaLPT_Click(object sender, EventArgs e)
        {

            txtdataIn.Text   =   Convert.ToString(LPT.Input(0x378));
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
    }
}
