Default - ADVICE and LINKS
Refusing All Communication
Users with Wheel or Operator capabilities enabled can ADVISE, SEND, and TALK to terminals that have refused advice, user-messages, and links. To refuse messages and links from privileged users, use the TERMINAL INHIBIT command.
Typing RECEIVE During Attempted TALK
If your terminal has been set to refuse links and another user tries to talk to you by using the TALK command, both terminals will give a series of CTRL/G signals (ringing bells or beeps) indicating the refused attempt. If you give the RECEIVE LINKS command before these signals are finished, the TALK command will succeed.
Safeguarding Terminal Output
If you want your terminal to print a long file, without interference, use the TERMINAL INHIBIT command to prevent all classes of message from being received. Be sure to use the TERMINAL NO INHIBIT command afterwards to restore the previous condition of your terminal.
Implicit Refusal of Advice
If you give the REFUSE LINKS command, your terminal will be set to refuse advice also. However, the INFORMATION TERMINAL-MODE command may not display this setting unless you give an explicit REFUSE ADVICE command as well.
