Description

The dup data communications device is used only with the 2780/3780 Terminal Emulator. It has no programmable user interface.

When a system is generated for 2780/3780 emulation on UNIBUS host machines, the dup data communications device must be specified in the configuration file as dup0.

To boot a UNIBUS device having 2780/3780 emulation, the dup must be specified in the rc.local file. This device is specified by removing the comment sign from the command line already placed in the rc.local file:

#/etc/bscconfig dup0 bsc 1

The dup data communications device is used with the DF126 modem.
