The method used to check that the LDT/LDS card configuration and the DECT synchronization
clocks wiring are correct, rests on the contents reading of some accesssibles registers on these
cards.
The accessible registers are not the same ones for LDT and LDS card.
The command vport must be used under "enter command" prompt with following syntax
VPORT ADR=aaaa GP=xx CLX=y
with: aaaa=register I/O address
xx=cluster number
y=LDT/LDS card number
