- Does anyone know how to chain into the Com1: interrupt under Windows 3.1?
- I've followed the suggestions and examples from the Microsoft Developer's
- Network CD's and still have no success. If I chain into the interrupt
- vector, execute my interrupt handler and then execute the original
- interrupt handler routine, Windows steals the vector back! I've only
- tried this running under the Enhanced 386 mode where the Interrupt
- controller is virtualized.
-
- The Microsoft examples work fine for the keyboard interrupt vector but
- not the Com vectors.
