- Hi There Windows Gurus,
-
- I'm about to write my first windows program. Actually, I want to
- port a DOS communication program I wrote, to Windows. I'm an experienced
- DOS programmer, now learning about Windows (God knows it ain't easy).
-
- Here are some facts on the communication program I wish to port to
- Windows. It doesn't use BIOS or DOS services, but directly talks to the
- UART. It takes over the proper INT vector, and the Interrupt Service
- Routine simply places incoming bytes in a buffer.
-
- Question 1) I beleive I can build the Windows program using the 4
- following segments; Could this work ??
-
- CODE segment #1. Interrupt routine saving incoming bytes to a buffer.
- DATA segment #1 The program's data.
- DATA segment #2. Buffer to save incoming Bytes.
- CODE segment #2. Process the bytes saved in buffer.
-
- Question 2) What is the best way to implement an Interrupt Service
- Routine for a serial communication port under Windows ?
-
- Question 3) Which segments would be Fixed | Movable | Discardable ?
-
- Thanks for helping me set my ideas straight.
