There is a flag in the CC2 byte (you can see where we handle this on
line 863 of session.c in the version 0.16.1 source).  If this bit is
set, it means to beep when you update the display.  There are various
other places where we beep, but that is the one which would be related
to the DDS ALARM.  The CC1 and CC2 bytes are sent with the `Write to
Display' command, the CC1 flags are supposed to be handled before the
update and the CC2 is handled after.

For some reason, it is just called the `Functions Reference', it is
available here:
http://publib.boulder.ibm.com:80/cgi-bin/bookmgr/BOOKS/CO2E2001/CCONTENTS

This is actually the functions reference for the 5494, but it contains
everything from the 5250 Functions Reference that I own and some more.
