-
- One simple way to release clock cycles it is to make your program
- "DESQView-aware", and then loading the OS2SPEED utility (found in Hobbes).
- This utility recognizes the DV interrupt for releasing time-slices and
- does the same for the DOS box.
-
- There is an interrupt to use for releasing time slices under DV.
- Unfortunately, I dont remember what it is, but you can get the complete
- DV interrupts from a file on SIMTEL20 or ask in the desqview newsgroup.
-
- I am using MS-KERMIT which is desqview aware in a dos box, with the
- OS2SPEED utility loaded and it works great.
