README.md

GTK DMD 5620 Emulator

This is a GTK+ 3.0 implementation of an AT&T / Teletype DMD 5620 emulator.

Status

Version: 1.3.0

This is an actively developed project.

Dependencies

The executable has the following dependencies:

Rust toolchain version 1.50 or later
GTK+ 3 (libgtk)
GDK Pixbuf 2 (libgdk-pixbuf)
Cairo 1.15+ (libcairo)
Glib 2 (libglib)

Building

Ensure that the Rust toolchain is installed. This is most easily done using the rustup installation script. For more information, see https://rustlang.org/ and https://rustup.rs/
Type make

This new build process is still somewhat experimental. The Makefile attempts to ensure that the Git submodule dmd_core is updated and built, but this has not yet been widely tested.

Usage

The terminal emulator uses the Telnet protocol to communicate with a remote host.

dmd5620 -v | [-d] [-s <shell>] [-n <nvram_file>] [-- <gtk-options> ...]

shell is the shell to execute. If not specified, the user's default login shell will be executed.

nvram_file is the name of a file in which to store the contents of NVRAM. This will preserve the state of the NVRAM between runs.

Key Map

Certain keys are mapped to special DMD5620 function keys.

F1-F8 are mapped directly to terminal F1-F8
F9 is mapped to the DMD5620's SETUP key.
Shift+F9 is mapped to the terminal's RESET functionality. This can be used to get out of any jams.

Changelog

Version 1.3.0

Removed telnet support.
Added local shell execution.
Added man page.

Version 1.2.0

Upgraded to libdmd_core 0.6.3
Improved timing further (loading with 32ld works now)
Fixed build in CentOS. Should build cleanly on Fedora, RedHat, Ubuntu, and Debian now.

Version 1.1.0

Upgraded to libdmd_core 0.6.2
Removed the need for Rust to compile!
Improved timing.
Fixed a Telnet bug that prevented BINARY mode negotiation.

To Do

Local serial line support is not yet implemented.
