VFP Timers

[barrymavin]

You can do this programatically by creating a Timer object as was previously mentioned.

Alternatively you can have timers on the app, pages, sections and fields all with a configurable timer interval. Note that timers only fire when your app is in runtime mode not in design mode.

Rather than polling it may be more responsive to handle a callback depending on what you use to handle the serial communications. As ws mentioned previously you can do this in Python and integrate it into your VFP code.
