[comp.lang.pascal] Toggle TextAttr 7th bit Blinking/Bright background

ZCCBJSB%EB0UB011.BITNET@cunyvm.cuny.edu (Josep Sau B.) (05/22/91)

From interrupt list INTER191.ZIP I've got this interrupt:

 INTR $10
 AX = $1003
 BL = $01   7th bit of attribute blinking enabled
      $00   Idem disabled, allows bright colors background.
      $00

I've just tested it in a PS/30 with SVGA, and works ok,
wonderful backgrounds with LightGray..White, using Turbo:

VAR r :REGISTERS;
...
r.AX := $1003;
r.BL := $00;
INTR($10,r);
...

Does anyone know of possible hardware or system model
incompatibility ?
