- | GTTY (glass teletype) is a lightweight terminal emulation program written by Lyle Bickley to serve as a console for PDP-8 machines. The current iteration is an MS-DOS program that seems to run well in DOSBox. Features include automatic switching between 7M1 and 8N1 serial protocols depending on whether the program is functioning as a TTY terminal or emulating a binary PT punch. | + | GTTY (glass teletype) is a lightweight terminal emulation program written by Lyle Bickley to serve as a console for PDP-8 machines.
