Hi, I would like to access Io ports from a user land application. I found a MINI HOWTO giving an exmaple using ioperm / iopl and then outb, inb. Searching the mips source code I see that sys_ioperm returns "ENOSYS" function not implemented. Does anyone know how to implement ioperm / iopl type functionality on a mips system. Any example code would be appreciated. Wayne. __________________________________________________ Do You Yahoo!? Yahoo! Tax Center - online filing with TurboTax http://taxes.yahoo.com/
