Arduino serial console

I have a graphic LCD with the KS0108 controller and I’m using the library from the Arduino Playground.

I’ve tried to output text from the serial port to the LCD and that works.
Now I want to output multiple lines of text that start at the bottom of the LCD and scroll op like the command prompt in windows.

When i run this code only random characters are outputted to the display:

#include <ks0108.h>
#include <Arial14.h>
#include "SystemFont5x7.h"
#include "M2Icon.h"

int regel=0;
char* regels[]={"                      ","                      ","                      ","                      ","                      ","                      ","                      ","                      "};
char temp[22];
void setup(){

  GLCD.Init(NON_INVERTED);   // initialise the library
  GLCD.DrawBitmap(M2Icon, 0,0, BLACK); //draw the bitmap at the given x,y position
  GLCD.SelectFont(System5x7);       // select fixed width system font 

void loop(){ // run over and over again
      char b[2];

void redraw(){
  for(int y=0;y<8;y++){
    Serial.print("Writing line ");
    Serial.print("Line contains: ");
