SoftwareSerial with ATTiny84 using ATtiny library

I'm not sure what you're asking about and certainly not in the last section.

To get started with Knockbang, here is what I do:

In _TinyISP_BuildOptions_h i put these lines:

#define RELAY_SERIAL_ENABLED  0
#define RELAY_KNOCK_BANG_ENABLED 1

And in TinyISP I comment this:

//#include <SoftwareSerial.h>

Then I upload this sketch to the ATtiny85:

#include <TinyDebugKnockBang.h>

int x=0;

void setup( void ) {
  Debug.begin( 250000 );
 }

void loop( void )
{
  Debug.print("Test-");
  Debug.println(x++);
  delay( 1000 );
}

Open the serial monitor @19200 and enter !
