The method is as follows: type the type command. It willwait until tty5 is dialled up. When the phone answers, depress the interrupt button after paper has been loaded,and the first file will be typed. spaces out to the end of a sheet of paper and waits until the interrupt button isdepressed before beginning each new file.
