may you help us?
we're trying to control a frequency inverter with rs-232 serial port,but
to disable the uart interrupts we usualy clear the second register from
the uart to zero.with an outportb(3f8+1,0) but when we've ported this
code to gnat the register is replaced to zero but the action of disable
don't occur.May gnt interfering with this?We accept any suggestions
another question,how can we make interrupt handling with gnat when we
trying to make an access to a protected procedure gnat crashes and show:
"GNAT BUG DETECTED"
thanks a lot.
