Abstract

This typewriter terminal incorporates an automatic dial device for effecting the automatic transmission of messages to designated stations. Messages to be transmitted are entered on keyboard 11 to page memory 13 and are subsequently stored a page at a time on magnetic media recorder 15. Each message to be stored is prefixed with the phone numbers of the terminals which are to receive the message. If the receiving terminals require a sign on procedure, the sign on procedure also prefixes the data. An end-of-message signal is stored at the end of the data message.

Typewriter Terminal Incorporating Automatic Dial Device

This typewriter terminal incorporates an automatic dial device for effecting the automatic transmission of messages to designated stations. Messages to be transmitted are entered on keyboard 11 to page memory 13 and are subsequently stored a page at a time on magnetic media recorder 15. Each message to be stored is prefixed with the phone numbers of the terminals which are to receive the message. If the receiving terminals require a sign on procedure, the sign on procedure also prefixes the data. An end-of-message signal is stored at the end of the data message.

Once a plurality of messages have been recorded onto magnetic media, a playout mode is initiated, causing the first message and its corresponding prefix information to be read into page memory 13. Control 17 effects the sequential gating of the phone number portion of the message to auto-dial unit 19, which provides signals to telephone control 21 to effect connection with a remote terminal. Once connection is established, control 17 effects the gating of the sign on data to telephone control 21. Once the proper sign on has been recognized, control 17 effects the transmission of the data in page memory 13. When the end-of-message code is detected, control 17 effects an automatic disconnect and updates the information content of the telephone number message indicating that the corresponding data has been transmitted to that phone number. The procedure...
