- Hi, I am wondering about programming a serial communication programme in DOS
- but would like to make it "OS/2 aware". Thus I have the following questions.
-
- 1. Is there a way to detect if a programme is operation in OS/2 2.0's
- dos box ?
-
- 2. Is there a way a programme, running in OS/2 2.0's DOS box, can release
- clock cycles to OS/2 ?
-
- 3. What happens when a programme hooks onto the serial communication
- inturrupt as provided by DOS INT 21h ? Will a interrupt driven
- serial communication driver written this way be efficient in the
- DOS box of OS/2 ?
-
- The reason why I want to write an OS/2 aware programme in DOS mode is that
- I cannot afford an OS/2 based compiler just yet, and I really don't want to
- be forced into using C/C++ which is provided by the free GCC compiler.
-
- Good Health.
-
- Changhao.
