DS:DX -> '$'-terminated string

AL = 24h (the '$' terminating the string, despite official docs which state that nothing is returned) (at least DOS 2.1-7.0 and NWDOS)

^C/^Break are checked, and INT 23 is called if either pressed standard output is always the screen under DOS 1.x, but may be redirected under DOS 2+

under the FlashTek X-32 DOS extender, the pointer is in DS:EDX
