Both libqrencode and qrcode-terminal are capable of using ANSI escape codes for colored text to produce black and whites squares. Two space characters make about the right aspect ratio in an xterm window. I reinvented the same method myself a while ago, so it's funny how different people come up with the same idea. Haven't tried it on a VT100 terminal yet, but it should probably work there too.
