Hi again,

there where some obvious errors left:

···

--------------------------------------------------------------
def ae_6 session
  pdu, pduLen = session.read(5).unpack('cN')
  buffer = session.read(pduLen)
  
  calledAETitle, callingAETitle, itemType, itemLength =
      buffer.unpack('x4A16A16x35Cxn')
      
  contextName=buffer[72, itemLength]
  
  start = 72 + itemLength
  while start < pduLen
    start += getNextPresentationContext(buffer[start..-1])
    puts "Finish = #{start - 1} outside proc"
  end
end

def getNextPresentationContext(pdu)
  it, il, presContextId, itemType, itemLength =
      pdu.unpack('CxnCx3Cxn')
      
  abstractSyntax=pdu[12, itemLength]
  
  start = 12 + itemLength
  loop do
    return start if pdu[start] != 64
    
    itemLength, =pdu[start + 2, 2].unpack('n')
    transferSyntax=pdu[start + 4, itemLength]
    
    puts "id=#{presContextId}, AbstractSyntax =#{abstractSyntax},
TxSyntax=#{transferSyntax}"
    start += 4 + itemLength
  end
end
--------------------------------------------------------------

cheers
