We have noticed that TENEX systems use link numbers outside the allowed range. This is a violation of the official HOST-HOST protocol. This causes problems with some sites when attempting to establish connections with TENEX systems. We urge that this problem be corrected by bringing all TENEX systems into conformance with the established official protocol
