terminal-input-link:host_k12 — ordinary primitive
let the forth stdin-handling look for data-messages on this link too. These will be interpreted like messages that come from the interactive forth terminal. This can be used in an embedded systems for a terminal session simulation. setting zero-sap will disable interpreting these incoming data-frames as keyboard-strings (so that the zero sap is therefore not usable for an input-link!). The startup default is zero.
