Is there any way to receive an event when a character arrives in the UART?

The discontinued WMCOMMNOTIFY event apparently did this before it was discontinued.

Hi Comrade,

I am using a thread with status testing (ClearCommError) and looking at cbInQue, which works fine.

I would rather use events.

Thanks,

Mike

comrade,

Could you post an example using "WaitCommEvent"

I have an app using WaitCommEvent to monitor for incoming serial data, < 100 characters, and it is working. But I've had to use some ugly code to get the notification of the next event. I don't send any serial data, just monitor for incoming.

Anything could be helpful.

Thanks in advance,

farrier

It might take me a while to dig it up if it's on a backup CD.

So is your app working or do you need assistance with it? From what you said it sounds like it's working.

comrade,

My program does work! But, it makes me feel "dirty" to look at everything after the invoke ReadFile line. I start a thread to handle the serial "interrupt" It is triggered, I read the serial port and was not sure what the best way to reestablish the "waiting" state for the serial port. I just kept trying things, until it worked. Now I reset the event, create a new event, and WaitCommEvent, WaitForSingleObject, for the next data.


If you can find the code, great. But don't go to too much trouble.

Thanks,

farrier
