Hi!

You can know these informations without use any interrupts.
(Interrupts're very slow for me *:-)
Now, I'm giving a some addresses to you;
You can access these addresses by Turbo Pascal's Mem, MemW, MemL predefined
arrays. (see more info to Turbo Pascal ver 5.0 Reference Guide page 220)
(I dont know where is it in Turbo Pascal ver 5.5 *:-))

Address  Function                               Size
-------  -------------------------------        ----
 40:4A   Number of Columns on the Screen        Byte
 40:50   Cursor position page 1                 Word
 40:60   Cursor type                            Word
 40:84   Number of Rows on the Screen (minus 1) Byte

 Address values are in hexadecimal notation.

(see for other addresses and their fuctions to IBM Personel System/2 and
 Personel Computer BIOS Interface Technical Reference - Data Areas and ROM
 Tables pages 3.1 to 3.23)

Did I help you? Yes, I think! *:-)
