In the RSTS/E V9.4 Programming Manual (DEC Order Number AA-EZ09A-TC {
including AD-EZ09A-T1,T2}) the aboved problem is addressed: " In order to
increase the flexibility of Ethernet on RSTS/E, DIGITAL has provided a
direct interface to the Ethernet data link layer for RSTS/E users. This
interface resembles the interface provided for the DMC/DMR communications
devices, and can be programmed with or without DECnet/E on the system."
(page 11-3)

This allows use of both UNIBUS controllers (DELUA and DEUNA) as device XE:
and the Q-bus controller (DEQNA) as device XH:.
