This subfunction returns the current parent and child vectors in the HP-HIL physical device driver
headers. The address of a seven word (14 byte) table is passed to the subfunction. When the
subfunction returns, the buffer will contain the current vectors. See table 4.17 for the buffer
format.

This subfunction sets the parent and child vectors in the HP-HIL physical device driver headers.
The address of a seven word (14 byte) table is passed to the subfunction. The table contains the
new parent and child vectors for the drivers. The format of the buffer is shown in table 4.17.
