The wireless station uses a special lock to allow or prevent
the programming of UDKs. You can turn on this lock
through the wireless station’s VT220 firmware menus or
from the host (with a DECUDK device control string). The
lock affects all programmable keys. When using the lock
follow these guidelines:

unlocked before you can define them. You can only
unlock the keys through the wireless station’s VT220
firmware menus. If a key is locked and an application

the wireless station ignores the sequence.
" Lock the keys to prevent redefinition. You can lock
the keys through the wireless station’s VT220 firm-
ware menus or from the host (with a DECUDK
sequence). New key definitions are unlocked by
