Debug output console don't relay keypress

[Peter-Oestergaard]

Wrapping getch() for use in Lua:

#include "lua.h"
#include "lauxlib.h"

static int lua_getch(lua_State *L)
{
    int ch = getch();
    lua_pushinteger(L, ch);
    return 1;
}

static const luaL_Reg functions[] = {
    {"getch", lua_getch},
    {NULL, NULL} /* sentinel */
};

int
__declspec(dllexport)
luaopen_adventureAux(lua_State *L)
{
    luaL_newlib(L, functions);
    return 1;
}

Function using the wrapper:

function INKEYS()
    return string.char(lib.getch())
end

When calling the INKEYS() function the expected behavior is for the application to wait for a key to be pressed. And when it happens it will return a string containing the character.

This works if I run the application in a regular terminal.

The problem:
When running in the ZeroBrane Studio debugger the Output window just shows a prompt that echoes whatever characters I press.
