Hi Venki,
Well I guess it would be an option ... I would give that a try and if you run
into problems try with 0.6.0 in order to help track down if there's a
regression.
The Modbus driver is actually one we had an external driver in the past and
which is now replaced by a full implementation by us.

Hi Chris,.
Shall we use 0.7.0 version to resolve this issue.
