The ANSI standard lists ESC[4m as the code to produce an underline
> export TERM=ansi80x25
> printf "\033[4masdfasdfasdf"
produces green text, not underline text as stated in the standard.
If I put the same in c code, it works
#include <stdio.h>
int main() {
fputs("\033[4masdfasdf",stdout);
return 0;
}
I get underlined text.
Why?
