I tried to run Rob Tillaart's VT100 sketch where he defines OFF. BOLD, LOWINTENS, UNDERLINE, BLINK and REVERSE using the relevant ANSI escape codes. I am using PuTTY but the BLINK and the LOWINTENS do not work, the rest do The BLINK just gives a background colour of grey. Does that mean that PuTTY does not support them?
