- But my problems are others:
- 1. I own Win 3.1, but I do not own the 3.1 SDK (nor the manual)
- 2. I get the WM_COMMNOTIFY messages correctly, but when trying to read from
- the comm-port I always get only one (though I know there are more)
- character.
- 3. These charecters are (seemingly) arbitrary chosen from the comm-input
- stream. I don't know how, or better what mechanisms, read out correctly
- comm-port input after having received a WM_COMMNOTIFY message.
-
- Maybe you know some help ?

- Thanks in advance (again :-) ),
