I can only guess something upset the pic at an hardware level because i have changed nothing at the software level. (I have even glued the crystal to the crystal socket!)

Anyhow.... these nuggets..

Plugged indicates when the device is fully connected to the PC.
RX_READY indicates when a report has been received.
TX_READY indicates when it's OK to Send. The device is Plugged and the SIE is ready to accept data.
Do you an an example line for those?

Once upon a time getting data into the pic was fairly easy, now I have to keep the pic doing some monitoring of its io pins but at same time accepting commands from the fake comport, so seeing if any data was waiting, as it seems to have very little in the way of flow control would be useful. (what happened to the wonderful buffers and fifo's on real hardware!)
