Checking the "HP 9000 networking XTI programmer's guide" from 1995 there's no diagram. The application which was initially developed on a SystemV derived UNIX the Computer division of Philips Electronics had bought, used TLI. Taken over by DEC we moved to SCO UNIX still using TLI, moving to XLI on Alpha/Digital Unix. The nice thing of TLI/XLI is the poll(). A multi-client server can check a list of file descriptors AND indicate a timeout value for the poll(). Like in ret_cd = poll(tep->CEPlist, tep->CEPnumb, timeout); BTW putting in a bit of OSI, on SCO UNIX I use a DEC package which offers a TLI interface to an OSI TP4/IP stack. Even worked using X.25 as WAN. OSI TP4 and NetBIOS originally bought from Retix. >Date: Sat, 31 Aug 2019 11:41:40 -0400 >From: Clem Cole >To: Rudi Blom >Cc: tuhs >Subject: Re: [TUHS] dmr streams & networking [was: Re: If not Linux,then what?] >Message-ID: > >Content-Type: text/plain; charset="utf-8" > >It's the Mentant implementation that HP originally bought.
