Adapted from sbj's hci.dev.VCR code into agent form 1/22/98 - jjlilley
The VCR class controls the VCR currently connected to Bird "A",
by sending the appropriate addresses to the SerialIR class.
It also keeps status information: power on/off, mute on/off, and
tape status (play/pause/ffwd/rew/rec/idle). Of course, it doesn't
receive this information from the VCR, so when this class is
instantiated some status information is assumed. See below.
Commands are sent via the press() method, which acts like a finger,
pressing a button on the remote control. For instance, press("VOLUME UP")
raises the volume a notch. Other methods include hold(), which is like
press but the button is left down. release() clears the BIRD,
releasing any held buttons (including those from other devices).
setChannel(), for convenience, presses all of the buttons necessary
to set the VCR's channel to the number given.
Upon instantiation, the power to the VCR is assumed OFF.
This means that few commands will work until a vcr.press("POWER")
is performed. When the power is turned on, mute is assumed OFF, and
the tape is assumed IDLE.

powerStatus
public boolean powerStatus
- This flag reports the guessed power status. It is modifiable, so
if it is wrong it can be changed by an outside class. If another class
sets this to true, it should also set muteStatus to false,
and tapeStatus to 0.
muteStatus
public boolean muteStatus
- This flag reports true if the VCR is "muted".
tapeStatus
public int tapeStatus
- This flag reports the tape status. Here are the meanings of the values:
- 0 idle
- 1 playing
- 2 paused
- 3 fast forwarding
- 4 rewinding
- 5 recording

getMuteStatus
public boolean getMuteStatus()
throws RemoteException
- Specified by:

setMuteStatus
public void setMuteStatus(boolean muted)
throws RemoteException
- Specified by:

selfDescription
public static String selfDescription()
setPowerStatus
public void setPowerStatus(boolean on)
throws RemoteException
- Use this to set the power status if it's wrong
- Specified by:

release
public void release()
throws RemoteException
- Releases a held signal, if there is one, from this SerialIR object.
If no signal is being held, then this method has no effect.

setChannel
public void setChannel(int channel)
throws RemoteException
- This sets the channel to the specified integer, by pressing the
buttons in order, followed by ENTER. A one-second delay seperates
the presses.
Channels less than 0 trigger a VCRException.
