The radio must be configured one of two ways:

1)  As a Point to Point master with FreqKey = 4
       For use at Santa Cruz with ESPmack

2) As a MultiPoint Master with FreqKey = 2
       For use at M0 with ESPbruce and ESPneo

After you've plugged in the radio, antenna and power supply...

0)  Connect the radio to the laptop's serial port.
1)  Power on the laptop
2)  Log in as user esp
3)  bring up the GUI
  $ startx

4)  Bring up two terminal windows
5)  In one change to the root user
  $  su

6)  In this root window, start picocom to configure the radio

#  picocom  --baud=19200  /dev/freewave

7)  Toggle the radio's configuration switch
      Configure the radio appropriately:

    On the Operation Mode menu select either
      Point-to-Point master for Santa Cruz
         or
      Multi-Point master for M0

   On the Radio Transmission Characteristics menu
     Select Freq Key of
       4 for Santa Cruz
       2 for M0

8)  Exit radio configuration mode by pressing ESC at its main
configuration menu

You should now see a link on the radio if the other side is up.

9)  Exit picocom with the key sequence:

    Ctrl-A    Ctrl-X

10)  Start the appropriate networking stack on the laptop

    #  ifup   ppp0     #for Santa Cruz
    #  ifup   sl0        #for M0

11)  In the other (esp user) terminal window

    $  ssh  ESPxxx.radio

where xxx is either mack, bruce or neo

This should get you an esp user shell on the desired machine

When you move between mack/bruce and neo, you will need to switch both
the freewave
radio configurations and the laptop networking.  Before you can
reconfigure the radio,
 you must bring down the laptop's current  networkinginterface to it.

12)  In the root window:
    #  ifdown  ppp0   #if you've been talking to  ESPmack.radio
    #  ifdown sl0      #if you've been chatting to ESPbruce.radio or
ESPneo.radio
Then, go to step 6
