Re: [Owfs-cvs] Using OW.pm in a loop fails with : Compilation segmentation fault

[Christian M. <ma...@ma...>]

I should perhaps tell you that it has always been able to open multiple
connections at the same time.
OW::init("-u -s 192.168.3.1:3001 --fake 10")
This will result into /bus.0 /bus.1 /bus.2 directories where you can =
address
each connection if you like.
The root-directory will show ALL devices found from all connection.
