After OS390 V2R8 , you can use HPR/IP or Entrprise Extenter. It's the same
for SNA Protocol, just the 1,2 and 3 couche OSI are UDP. You can donwload
802.2 protocol between a router cisco 2500 and a sna-server or X25 server
and forward with snaswitchinf to the host or directly to the host. Yon don't
need hardware to make SNA or QLLC, more product emule this protocol ===>
HNAS fo X25 (SOLVE,VIRTEL,etc..) and E.E for SNA 802.2

Ok work needs to be done on device option one.
What about a generic driver that interfaces to existing installed
hardware and software for SDLC equipment? something similar to the
tapecopy utility.
I can't see the point here... Tapecopy is really an offline utility.. Using
offline utilities for online protocols doesn't make much sense to me..
For option 1 (Lan DLC) though LCS, I don't think the problem is DLC access
(we just use frame layer) - but rather the LCS portion.
Interfacing option 2 through an Ether DLC wouldn't be too hard.. The problem
is emulating the SDLC device (basically, an ICA).
So the real problem is not communicating with the outside world, but rather
passing proper data in and out of the guest in hercules in a way that is
consistent with what is expected by programs running under hercules, from
such devices.
