interrupt driven tx
In the isr, keep pushing out data from cbuf. If empty, disable the
To translate that into CSP signal flow, do the following:
- If there are more characters to transmit, keep going.
- When done, send a signal on the shared interrupt pipe

Trick was to use both transmit ready and transmit done interrupts.
Next step is probably to also do the packet decoding in the interrupt.
Or maybe not. Let's stick to bytes.
