calling the ReadFromLine function triggers an attempt to establish a connection unless the connection has already been established
in case of error (broken or closed TCP connection) the function ReadFromLine returns a value 2^32-1, i.e. 4 294 967 295
subsequent calling of the ReadFromLine or WriteToLine functions will cause an attempt to re-established the connection
if the connection is established, the requested operation is executed (ReadFromLine- reading data, WriteToLine - writing data)
if multiple IP addresses (separated by a comma or semicolon) are configured in the line configuration, the KOM process cyclically uses them to establish a connection to these IP addresses
