Ok, so the passive adapter.

Ok, so owfs and fuse works. The problem is purely with reading the serial
device.
Possible reasons are:
1. Wrong device name
2. Wrong device permissions
3. Wiring/voltage problem
Even "cat /dev/ttyS0" does not show any information on ttyS0 port.

Not surprising. You could try "ls -al /dev/ttyS0" to see if it is a correct
character device. Since all 1-wire devices are passive, the bus master 9097,
generates all the traffic.
So, I am at a loss ... Is DS2781K a owfs supported device ... or am I

Yes the DS2781 is supported.
Again, the "owfs --error_level=9 --foreground -d /dev/ttyS0 /mnt/1wire"
would give more information
