DAL 1.3.5: AsyncCTB (X.25) Only for VAX or A/UX DAL Servers

A DAL 1.3.5 document indicated that X.25 support is available for DAL to VTAM and TSO servers. Is this true?
The AsyncCTB (X.25) network adapter will only go to VAX or A/UX DAL servers.

The only "async-type" input that IBM mainframe servers accept is dial-in to a Protocol Converter that supports VT100 terminal-type access.
