IBM 2780 and IBM 3780 Features 

This section lists the features of the IBM 2780 Data Transmission
Terminals and the IBM 3780 Data Communication Terminal.

IBM 2780 Data Transmission Terminal 

The IBM 2780 Data Transmission Terminal is an IBM remote batch processing
terminal that uses IBM Binary Synchronous Communications line protocol
(BSC). It has the capacity to:

 *  Transmit or receive in ASCII, EBCDIC or 6-bit transcode.

 *  Accept horizontal tabulation codes (optional).

 *  Accept vertical forms control codes.

 *  Transmit or receive data in the transparent mode.

 *  Truncate short records.

 *  Transmit or receive blocked data.

IBM 3780 Data Communication Terminal 

Like the IBM 2780, the IBM 3780 Data Communication Terminal is a control
unit with a set of input and output devices.  It has the capacity to:

 *  Transmit or receive in ASCII or EBCDIC.

 *  Accept horizontal tabulation codes.

 *  Accept vertical forms control codes.

 *  Transmit or receive data in the transparent mode.

 *  Truncate short records.

 *  Compress blank fields in data.

 *  Transmit or receive blocked data.

 *  Interleave data passed between the communications line and
    input/output devices through the use of two 512-byte buffers, thereby
    increasing overall transmission efficiency.

 *  Generate Wait-before-transmit ACKnowledgement (WACK) and Temporary
    Text Delay (TTD) control character sequences when it is temporarily
    unable to transmit or receive data.

Information for the IBM 3780 Data Communication Terminal.
