We need HELP:

1: We want to use an MS-DOS parallel port as some kind of userport.
   Therefore we have to be able to access this port directly and to change
   the input/output of the datalines/statuslines.
   We want to know whether this is possible and how to access the port.

2: Borland's PUTIMAGE is not fast enough for our application. does anybody
   know how to access the video ram of a VGA card? As far as we know the
   first plane starts at A000:0000 where do the other 3 planes start?

3: We have problem's setting the mousecursor on a VGA graphics screen.
   Does anyone know where we can find some code doing this in turbo pascal

   We are using Turbo Pascal 5.5 on a 286 2MB AT

Thanks in advance,
