Hi,
I am still trying to make my card reader work. I even found a long cable
and a RS232 diagnostics box. In my current serial.c/vl.c version I correctly
handle DSR and DTR. I can demonstrate this nicely with Linux+gtkterm
and Windows XP and Hyperterm. Before I add more features please help
me with the follwing problem:
the about page says: QEMU emulates a full system (for example a PC)
In a PC system the OUT2 bit of the MSR enables the forewarding of
interrupts to the PIC. So I currently changed the serial.c implementation
from
if (s->iir != UART_IIR_NO_INT) {
s->set_irq(s->irq_opaque, s->irq, 1);
} else {
s->set_irq(s->irq_opaque, s->irq, 0);
}
to
if (s->iir != UART_IIR_NO_INT && (s->mcr & 8)) {
s->set_irq(s->irq_opaque, s->irq, 1);
} else {
s->set_irq(s->irq_opaque, s->irq, 0);
}
Windows 2003 is paranoid enough to set also OUT1 (although my
hardware bible says that this one is not connected).
Is my code OK? Who knows better?
Yours Jürgen
