configure uucp between AIX and UnixWare7

I need to configure uucp between UnixWare 7 and AIX.
I have it working between SCO Openserver 5 and UnixWare 7 using TLI, and between OS5 and AIX using the TCP socket interface, But I cannot get it to work between AIX and UW7.
I presume I have to start a listener on AIX but I don’t know how.
