The 3770 is a family of desk console style terminals that offers a variety of keyboard and printer combinations as well as I/O equipment attachment and communications features.

The data interchange program (DFHDIP) supports the batch controller functions of the IBM® 3790 Communication System and the IBM 3770 Data Communication System. Support is provided for the transmit, print, message, user, and dump data sets of the 3790 system.

TSO/VTAM provides the capability of using TSO through VTAM®. TSO is a standard feature in MVS™ that provides conversational time sharing. The basic elements of TSO/VTAM are the terminal control address space (TCAS) and the VTAM terminal I/O coordinator (VTIOC). TCAS accepts logons from TSO/VTAM users and creates an address space for each user.

BREAK specifies, for IBM® 3767 and IBM 3770 terminals, the system can interrupt your input. For other terminals, it specifies that your terminal keyboard is to be unlocked to allow you to enter input whenever you are not receiving output from the system. The system can interrupt your input with high-priority messages.

One of the primary pieces of hardware, the 3745 /3746 communications controller, has been withdrawn [a] from the market by IBM. IBM continues to provide hardware maintenance service and microcode features to support users. A robust market of smaller companies continues to provide the 3745/3746, features, parts, and service.
