PL>Found while perusing Ralf Brown's list:
PL>INT 10 U - VIDEO - READ PEL MASK (VGA/MCGA)
PL>        AX = 1019h
PL>Return: BL = value read
PL>INT 10 U - VIDEO - SET PEL MASK (VGA/MCGA)
PL>        AX = 1018h
PL>        BL = new PEL value
PL>Experimenting with them shows that calling the latter function does funny
PL>things with the colours on your screen.
PL>The question: what is the PEL, what is its mask, and what is the purpose
PL>of the latter function ?
PEL is IBMs way of referring to a pixel. With that in mind these presumably
set a mask for writing pixels to the screen. With this you might
AND,OR,XOR,etc pixels on the screen with other pixels.
