<snip> > Somewhere around test 85 the Mac crashes badly. Even from user mode. That is strange. The kernel shouldn't really panic, unless you where running this process in kernel space. Trying to access an I/O port or hardware-mapped memory shouldn't give you a kernel panic from user space. The kernel should just reject it, and send a signal to your process. > I don't know if this crash would affect different serial ports or > non-SUB serial ports or whatever. > > Any thoughts? I think you have to use a device driver. Or you need to make your script run in kernel space, you can't access any HW from user space. http://developer.apple.com/techpubs/macosx/Darwin/IOKit/IOKitFundamentals/Ab out/index.html Tor
