Hi Ralph,
Is it serial/ASCII or serial RTU?
It seems difficult to do Modbus with Stream. Your protocol would have to worry about byte order, CRC, etc.

Subject: Modbus/serial using Stream?
Hi,
has anyone ever tried to talk to a Modbus server (Modbus/serial) using
Stream device?
I am trying to get my unresponsive units to answer me, and looking at a
working Modbus protocol file would really really help me.
I know there is Mark's modbus driver, but I was more comfortable adding
another protocol file instead of adding another software package.
Until now, maybe?!
Thanks a lot,
~Ralph
