Actually, Bash uses BIOS for console I/O.  For output, it calls
Int 29h, which on DOS simply calls Int 10h/AX=0Eh by default.  But
if ANSI.SYS or similar driver is installed, ANSI escape sequences
can be supported by Int 29h, but not by bare BIOS calls.

More precisely, Bash uses termios functions, and it's termios that
calls Int 29h.
