Example
With a display of:
I0 0.0 00000CTZ -I W 0.0 DII?
FHEQ AMPTD
Alphanumeric characters output will be:
100.000000MZ -140.0DM
Cursor value output (4th cursor from the left) will be:

= 16
Annunciator value output for FREQ and AMPTD will be:

= 32+1048 576=1048 608
Outputting the display could be used to output the currently selected special functions, or
to output the annunciator value to determine the current modulation source.
