modbus's Issues
Parsing error when 2 write commands are called in quick succession
Using the TCP Master code on a Fieldbus Accelerator with a Koyo Click, the following code throws a parsing error when processing the second request.

#require "ModbusMaster.class.nut:1.0.0"
#require "ModbusTCPMaster.class.nut:1.0.0"

TCP readWriteMultipleRegisters behaves differently than expected
The documentation states:
"This method performs a combination of one read operation and one write operation in a single Modbus transaction. The write operation is performed before the read."
However when I run the following code the read doesn't show the values I just wrote.
#require "ModbusRTU.class.nut:1.0.0"
#require "ModbusMaster.class.nut:1.0.0"
#require "ModbusTCPMaster.class.nut:1.0.0"
