I am trying to get isode working on a Sun running SunOs 4.0, Sunlink
MHS, OSI, and X.25.  I'm trying to understand how isode is interacting
with Sunlink OSI and X.25.  Can anyone tell me:

How does the tsapd pick up TP4 connections that come in from Sunlink
OSI?  If it dosn't, (and I suspect that it dosn't), then what is
listening to the network to pick up these REAL-NS network connections
that are destined for isode?  Or should I ask, what is listening to
Sun's transport to pick up these TP4 connections destined for isode?

Secondly, I'm having a problem with the tsapd with respect to X.25.
I start the tsapd with the following line:
/usr/local/etc/tsapd -a 031342023004500 -i 03010100
and I get this in the tsapd.log:
 6/27 14:11:55 tsapd    09318 (root    )  -a: unknown switch
This never used to happen under SunOs 3.5.

I stick the x.25 addresses into the isotailor file, and it seems to be
completely ignored.  X.25 calls with that CUD don't get sent to the
tsapd.  Here's the isotailor file:

ts_communities: realns intl-x25 internet

Here's my address from isoentities:

osisun          default         1.17.4.3.9.3.0 \
                NS+4700040034020108002001635400|\
        Internet=cos|\
        Int-X25(80)=031342023004500+PID+03010100

Any help would be appreciated.
