How to use com links in ITS

Com links allow terminal sharing between users.

Entering and exiting com link mode

Use ^_Cfoo to attach to terminal or user foo. An octal number specifies a terminal number. This works with any number of users.

Initially, input and output to programs is disabled, so users can type text to each other.

Use ^_N to detach from terminal sharing.

Using programs in com link mode

In com link mode, toggle program I/O with ^_I and ^_O. When I/O is enabled, programs can use the terminal normally.

Slaving terminals

Slaving a terminal means sending input to it from another terminal. When in com link mode, use ^_Sfoo to slave another terminal. To toggle sending it input, use ^_E. Doing ^_E will automatically slave the other terminal if there are only two terminals in the com link session.
