Using XTI interface on Redhat 2.4

Hi,

As a p.s. I don't have permission to browse the archive, so I cabn't see if
anyone has already answered this.

but here goes...

I have a legacy application that I'm porting to Linux from AIX. The
application uses XTI. I downloaded Lis, installed and invoked strms-up. The
test programs run fine. However on running a (simple) application I get

Function not implemented

when tring to connect or to listen.

I'm pushing timod using t_open with /dev/tcp and binding these prior
operations seem to work o.k.

When I try to conenct I get a failure in getmsg, the same if I try to
listen.

Can anyone help? or does anyone have a simple sample program that will give
me a steer.

kind regards

Rob
