off hook

off hook
The state that your telephone is in when you pick it up. In non-computer life, it usually means when the telephone connection is accidentally disconnected, such as "Someone must have left the phone off the hook." A modem that takes the phone "off hook" is taking control of the phone line, and it will usually then dial a phone number for you. When a telephone line is "off hook," you are not able to receive calls from other people. See also on hook
