SIO mode , better. Some strangeness with BASIC, still needs to test with SIO compiled CPM
SIO code changed to use the circular buffering used with the ACIA.
Similar bodge to the ACIA where the buffer reports nothing available whilst there is a char in the RX buffer of the SIO emulation. This prevents overruns.
Need to test with known good ROM. but Setting SIO appears to break boot.
