Well, this is what it looks like without my pppd asyncmap set to 0x0000000:

Async Map: L:00000000 R:ffffffff 00000000

When I set it to 0x0000000, i get this:

Async Map: L:00000000 R:00000000 00000000

So obviously it had an effect for Receive async maps and isn't bogus.

I'm guessing 0x000000 is mask all, and 0xfffffff is mask none.
