ATE enhancement: new AG_PLAYSOUND (105) command to force ATE client to play a sound file:
? TAB(-10, AG_PLAYSOUND); fspec, flags {rtnsts}; chr(127)
fspec and flags are the same as for the existing MX_PLAYSOUND. rtnsts may be set to non-zero if you want to get the return status in the keyboard buffer. Otherwise (if 0 or omitted), there is no response.
Note that fspec must be a PC native filespec.
