$ uisp -dprog=stk500 -dserial=/dev/ttyS0 -dspeed=115200 -dpart=atmega128 
--rd_fuses
Firmware Version: 1.14
Atmel AVR ATmega128 is found.

Fuse Low Byte      = 0x3f
Fuse High Byte     = 0x83
Fuse Extended Byte = 0xff
Calibration Byte   = 0xa0  --  Read Only
Lock Bits          = 0xc0
    BLB12 -> 0
    BLB11 -> 0
    BLB02 -> 0
    BLB01 -> 0
      LB2 -> 0
      LB1 -> 0

All the doc on ethernut.de seems to suggest that the lock bits should be 
flipped on.  But wr_lock isn't doing anything for me.  Can someone 
confirm that they *are* supposed to be on and suggest how to get them 
flipped if that's the case?
