The Prohibit DECnet Transport attribute specifies whether the DSA can use
 the DECnet OSI Transport protocol to communicate with DUAs and other DSAs.

 If the use of DECnet OSI Transport protocol is prohibited, then all
 communication will use the DSA's private RFC1006 implementation rather than
 DECnet's transports. If DECnet is running you will most likely not be able
 to use TCP/IP port 102 as DECnet will have allocated it.

 The DSA must be in state OFF when you set this attribute.

 Syntax:
 	SET  DSA PROHIBIT DECNET TRANSPORT <TRUE/FALSE>
 	SHOW DSA PROHIBIT DECNET TRANSPORT
