[comp.protocols.tcp-ip.ibmpc] Concurrent use of DECNET and TCP/IP on DEPCA card?

scottw@sequent.UUCP (Scott Williams) (05/31/90)

Got a fun question for you all...

Has anyone ever tried to concurrently run DECNET and TCP/IP on a PC
with a DEPCA card?  Anyone ever written a packet driver for the DEPCA
card--or will that even work with DECNET?  Any help is appreciated.
If there's enough interest, I'll post a summary.

Thanks!

Sorry, there's no packet driver for a DEPCA card, but there's lots of
requests for one...

DEC provides a software interface sharing scheme called DLL with PCSA
and DECNet/DOS.  Our PC/TCP and Wollongong's WIN/PC support it (DLL
came in an early version and a late version - I know we handle both, I
don't know about WIN/PC), with the minor restriction that we can't
handle 4bsd "trailer" packets if too many PCSA features are in use
(DEC only provides 8 "portals", and they don't always leave us the 5
we need to handle trailers as well as normal IP and ARP).  I don't
know of any freeware packages which support DLL.

DEC is apparently changing direction to support NDIS instead, but I
don't know if/when you can get an NDIS driver for the DEPCA.  If you
can get one, look through the archives for recent messages on who
supports NDIS.
