Can anyone explain how to poll a Microsoft Mouse, connected to Com1, from inside of Turbo Pascal (version 5.5)? I would like to be able to tell which direction the mouse is moviing, and which button has been clicked if any.

The mouses sends cursor values of up, down, left, right as extended codes;
that is, ReadKey sends a zero and then an H, P, K, R for up, down, left,
right. The right mouse button is an escape [char(27)]; the middle button
is an enter (char[13]); and the left one sends an F1 and opens a pop-up
menu that has F1 thru F10, /, and ?. The F1 - F10 are also two-character
extented codes like the arrow keys; after the zero you get 59 thru 68.
