Hi all.


Still playing with my interrupts.

Once you have set one up on the COM port, how do you temporarily disable it?

The manual, page 7, right at the bottom says: "Also remember to disable an interrupt when you have finished needing it - background interrupts can cause strange and non-intuitive bugs."

...we will say nothing of the other problem I was having...(DO/LOOPS thread)


Anyhow, in the case of the serial port, do I just CLOSE the port, and the interrupt is then disabled?

I am guessing this is the way to do it, but as I have made assumptions like this before, I thought I should ask.

So, I would assume that if I close the port, the interrupt will be cancelled, as there is no valid open port for it to work with once the port is closed.

I can then just re-open the port again with the interrupt when I need it - correct?

Smoke makes things work. When the smoke gets out, it stops!

Yes, that is exactly correct.

P.S. It is a change to see others creating bugs rather than me.
