Now, Emutos should be correct regarding the byte to expect after a soft
reset, and Hatari should be correct regarding the serial line's state just
after a cold start.
Amazing analysis and bugfix!!
Hatari and EmuTOS are now more accurate than ever :-)
BTW: Can we be sure that on real hardware the cold boot 0xf1 is not received
by the ACIA?
As I said previously, Atari TOS just waits a fixed time after sending 0x80
0x01. If 2 bytes arrives, I guess that it causes an receiver overrun, and no
one notices...
I thought that checking the RDRF bit before reading the data register was a
good idea to do clean things, but maybe I was wrong...
So I wonder if the current EmuTOS still works fine on cold boot on real
hardware.
