Let me back up and explain what we are trying to do and see if I
understand what needs to be in the IOCP to accomplish this.

We currently have a few dozen linux instances running within a
Z/VM Lpar.  They have VCTC links to the VM/TCPIP stack (acting
as the route to the internet).  We are trying to move the LINUX
instances to an IFL LPAR where they will eventually be defined on a
Vswitch (or a Guest Lan with a VM TCP/IP router).

To avoid having intermediate changes in the PIX firewall and Cisco
routers, we were trying to extend the LINUX CTC links from the
existing TCP/IP (in the non-IFL LPAR) to the IFL Linux machines
with real CTCs instead of the existing VCTCs.

Since we had RSCS, VTAM  and JES working with  SCTC device/links
we thought these links would also work with TCP/IP. (and it sounds
like it would have if we were talking from Z/OS TCP/IP to Linux TCP/IP)

What I think I'm hearing is that VM TCP/IP only supports BCTC (Parallel
Basic Mode CTC support over ESCON).

So now, if I define another pair of CHPID's (CTC/CNC) and
define the IODEVICES on these links as BCTC units, then I think
I'm hearing that the VM TCP/IP in the non IFL LPAR should be able to
communicate with a LINUX quest in the IFL LPAR.

I think the ccw_chan_mode parm in SLES specifies the type of CTC
link.  I think "0" would correspond to BCTC.

>CCW_CHAN_MODE="0"

If we're still off base we are open to further clarification.
