Tricky, tricky...

The interactions between the various buffers in the TAsyncSerTool seem to be clear now. I reverse engineered the EmptyInputBuffer method more thoroughly and found out that the comm tool tries to get as much data into the NewtonScript buffers. There is still something to do about data which won’t fit… it looks like the async tool will lose some of that data because it might be overwritten. Or maybe it will use flow control. Anyway, I’ll just store it in an intermediate buffer which is hopefully big enough for all higher level protocols. For OBEX, it is 2k, and PPP should be happy with 1.5k. Having this now out of the way I can continue working on the Bluetooth setup application.
