- Hello, All:
- I am using Windows 3.1 as an integrated programming environment
- for a microcontroller. The MCU board communicates with the PC
- through COM1. At one time I was able to use Kermit for DOS in its
- own window along with a DOS command window. I would edit
- in Windows Write (not very good for programming), compile
- in the DOS command, then see the results in my Kermit window - beautiful!
-
- This is how I download to the MCU:
- (Kermit is set for COM1)
-
- 1. In Kermit window, the MCU is put into load mode (it remains in Kermit)
- 2. In the Dos window, I type
- type myprog.s19 > com1
-
- That used to work OK. One time I got a contention error message
- from Windows for COM1, but I ignored it and eventually the problem
- just vanished. Then I noticed that line #2 above suddenly stopped
- working after I run Procomm (set for COM3) in the DOS command window.
- I would reset, restart Windows, and everything is fine again.
-
- But today it won't do it at all. I still get a good DOS command window
- and the Kermit window still talks to the MCU. But the DOS command
- window can't talk to COM1 at all. I haven't changed any setting in
- Windows throughout the whole time.
-
- Does anyone have any ideas why this could be happenning?
-
- thanks
