Remarks
This class realises the Modbus ASCII protocol using TCP as transport layer.
It provides functions to establish and to close a TCP/IP
connection to the slave as well as data and control functions which can
be used after a connection to a slave device has been established
successfully. The data and control functions are organized
different conformance classes.
Using multiple instances of a MbusAsciiOverTcpMasterProtocol class enables concurrent protocol transfers using multiple TCP/IP sessions (They should be executed in separate threads).
