Class to emulate a DEC VT102 terminal
The VT102 class provides emulation of most of the functions of a DEC VT102 terminal. Once initialised, data passed to a VT102 object is processed and the in-memory “screen” modified accordingly. This “screen” can be interrogated by the external program in a variety of ways.
This allows your program to interface with full-screen console programs by running them in a subprocess and passing their output to a VT102 class. You can then see what the application has written on the screen by querying the class appropriately.
