[oopic] Re: How to use oSerialL for reception of data ?

Hi Dennis,

yes, I've been reading that part of the manual over and over ...
The scary part is where it says : "...while the oSerialL Object is
waiting for incoming serial data, the program flow is stopped".
I don't want the program flow to stop, my program has other tasks to
do while it should receive the serial data in the background (event-
driven).
Is there a way this can be done ?

Thank you,
Patrick
