The "VERIFY" command(key2) compares the slaves' memory contents with the master
and also, for some devices, with the settings in the programmer.

This command also make a new checksum calculation for the master and update the 
display. If the value changes, a leading "*" character will go with this new value and 
a long beep will be issued to warn the operator.

If the device use the Protect-Setting-Byte(PSB) field, it will be verified at the last.
