Hallo,
some programm with source uses giveio.sys to access the parallel port. You can find the source for giveio.sys e.g. in the avrdude package. We have code in dlls/winedos/ppdev.c to emulate the directed access on the parallel port to accesses to /dev/ppdev.
However this code is not called for WIN32 code. So after starting giveio with loaddrv.exe supplied with giveio
wine loaddrv.exe start giveio
starting giveio... ok.
wine javr.exe
crashes when the outb access happens: javr [<filename>] [-p<port>] [-f<fusefilename>] [-e<eepromfilename>] [-L] [-V] Allocated flash buffer of 128K Using giveio.sys to gain port access to 0x378 trace:seh:raise_exception code=c0000096 flags=0 addr=0x4014b6 trace:seh:raise_exception eax=00000000 ebx=00000000 ecx=00000378 edx=00000378 esi=00000378 edi=00110388 trace:seh:raise_exception ebp=0072fe50 esp=0072fe50 cs=0073 ds=007b es=007b fs=0033 gs=003b flags=00010246 trace:seh:call_stack_handlers calling handler at 0x7eddc5bc code=c0000096 flags=0 trace:seh:MSVCRT_signal (4, (nil)) wine: Unhandled privileged instruction at address 0x4014b6 (thread 0011), starting debugger... trace:seh:start_debugger Starting debugger "winedbg --auto 16 56" trace:seh:call_stack_handlers handler at 0x7eddc5bc returned 1 Unhandled exception: privileged instruction in 32-bit code (0x004014b6).

MS msvcrt.dll also supplies outb().
What is the policy to handle outb() and friends?
Thanks
