Re: COM Port Interrupt stops interrupting

Hi,
     I'm trying to read, parse and test data from a serial device. I wrote two procedures called ReceivePort and IntitalizePort. The IntializePort intializes the com port and enables the COM interrupt. When the interrupt occurs, it calls the ReceivePort procedure. I call  the InitialzePort procedure from a Test. If I run the test it only responds to 1 interrupt and the test stops.  How can I keep the Interrupt alive to respond to more interrupts?
Thanks,
Paul

ATEasy runs the test and closes, If you want to keep it alive add a Modal Form to your application or loop endloop to keep it running. See also the ComChat example.

Re: COM Port Interrupt stops interrupting

I found that Ateasy loops sometimes are consuming lots of processor time.

loop
   sleep(5)        !gives the interrupt routine some time
endloop

will do the job.
