	I am involved in research in the construction of software
tools for authors of Computer Based Learning materials, and am having
a problem with receiving data from a videodisc player, driven from the
serial port of an IBM clone (Apricot Xen-i).

	I can initialise the port and send commands to the player
(using BIOS int 14h) but incoming data is not buffered so I can't
recieve frame numbers etc back from the player.

	Does anyone have any knowledge of this problem, or know how I
can write a serial input buffer to store incoming data? I usually
program in C, and have only limited experience of assembler.

	Another, unrelated problem which I am trying to solve is the
use of graphical/text images from MicroSoft Paint/Write. I would like
to be able to display these from within an authoring language by
calling a C routine to display the image. At the moment I can only
view such images from within MS Paint/Write , or print them out. Is
this possible - presumably I would need details of the encoding
algorithm??

	Thanks for any help !
