Some of the stuff we write at work could probably count as 'drivers' for a variety of modems. (They're more use-level than OS level however.) Each driver knows how to start each modem, how to (frequently) query the modem for data we need (signal strength, rx/tx speeds etc,) and also check to see whether the modem is actually providing connectivity. This latter is performed within the driver in a separate thread pinging an address once a second. I suppose that counts as concurrent tasks. -- PJH http://shabbleland.myminicity.com/tra http://www.chavgangs.com/register.php?referer=9375
