Multiple questions on MS-DOS

[L-28C <kixdemp@...>]

Hello everyone!

So I finally got Lua to compile under DJGPP... Now I have a few questions:

1) Is there any game dev library on this platform? Can LuAllegro somehow 
be compiled here?

2) How do you send escape sequences (like \x1b in C)?

3) [Example] How do you make command-line progress bars without ANSI? I 
see many programs using them, however I don't know how they do it... I 
thought "send multiple backspaces and redraw it", but that would cause 
flicker wouldn't it?

Thanks in advance!
