Activities

If you don't object, you can extends your knowledge of this hour's topics with the following activities:

• Create an AcousticModem class with a speed of 300 and its own connect() method.
• Add a disconnect() method to one of the classes in the Modem project, deciding where it should go to support modem disconnection in cable, DSL, and acoustic modems.
