It's intended to be adequately featureful and straightforward for mechanical purposes, not intuitive. > oskit_dump_devices() dumps following tree for sio devices: > > Current hardware tree: > isa.isa Industry Standard Architecture (ISA) Bus > 0x02f8.sio PC serial port driver > > So it should be "@>:isabus@=sio", right? It depends what you want. @foo means "position string foo". @isa@0x02f8 means exactly the second line given that tree above. @>:isabus@=sio would find the first sio device at whatever address, on any isabus no matter how far down from the root bus. So if /dev/ttyS1 should be "the COM2 serial port given canonical hardware", then @isa@0x02f8 is right. If it should be "the second port using the sio driver on the first isa bus", then @>:isabus@+1=sio is right. We don't have a proper COM interface for serial devices, but if we had one and you wanted "the second serial port in the system", then @+1>:serialdev would be right. _______________________________________________ Bug-hurd mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-hurd
