  replyLen bytes of reply are copied to reply.
 \item[availableRS232] returns 1 if data is available, o if none is available 
  and a negative value if an error occurs.
+\item[availableNetRS232] returns 1 when data is pending at the network
+reader for this port, else 0. This function also resets the network reader for 
+further use. This could lead to trouble if pending data is not
+directly followed by a read.  
 \item[getRS232Error] gets a string representation for the error code 
  iCode.
 \item[initRS232] tries to close and reopen the RS232 connection. This is 
  useful for the automatic fixing of communication problems encountered.
+\item[createRS232] creates a new rs232 data structure with all
+parameters at  default values. The connection is NOT opened.
