hi all,
Sorry for cross posting, but perhaps hackers is a better list than
multimedia for this topic.
i am trying to port my old assembler soft for Dos to FreeBSD.
i need to write and read directly to the midi and scsi device.
when i try something like this i receive a sigbus error
SORRY, i am NOT nor a C nor a FreeBSD expert!!!
all i know is Assembly language!
i made some search in the devel handbook and did not found the solution.
What is wrong here?
Can you enlight me please?
I think you need to open /dev/io before your program can execute I/O
instructions.
