Version 2.8 (2009-11-16) * Default baudrate is now 19200 as per Modbus standard. Version 2.7 (2009-06-04) * Corrected help and range check for -a parameter Version 2.6 (2008-10-30) * Added option -0 for PDU addressing and option -e for Enron/Daniel 32-bit mode. Version 2.5 (2008-04-03) * A return code of 1 is returned if operation was not successful otherwise 0 * -c parameter now accepts a value of 100. * Added time-out command line parameter. * Retry count is now 0 for serial protocols (was 2 before). Version 2.4.0 (2006-10-20) * Default parity changed to even as per Modbus standard. Revision 1.17 (2005-06-07) * Using the -i command line parameters returned an error message in ealier releases. Version 2.2.1 / Revision 1.16 (2004-09-22) * Using the -d and -s command line parameters returned an error message in earlier releases. Version 2.2 / Revision 1.15 (2004-04-25) * RTU over TCP protocol added, which is also known as encapsulated RTU. * Recompiled against 2.2 release of libmbusmaster. Version 2003-05-20 * Recompiled against 2.0 release of libmbusmaster. * RTU/ASCII: Added RS-485 mode for Win32, QNX and Linux platforms. * ASCII: Fixed casting bug which caused protocol error when transmitting FF. * MODBUS/TCP: Time-out applies now also when connecting to a server, tolerate a zero address field in an exception reply, fixed auto-retry. Version 1.2 (2002-11-19) * Terminates in case of a closed TCP/IP connection. * Some error messages changed. * Changed command line options for holding and input registers. -t4 is now holding register, -t3 input register. * Retry option is now working. * --version paremeter introduced. * Retries fixed. * -p parameter for MODBUS/TCP introduced. * Default parity changed to NONE. * Based on FieldTalk v1.3. Version 1.1 (2002-07-15) * Reference index print-out for 32-bit values corrected. * Based on updated FieldTalk library which fixed issue with time-out monitoring Version 1.0 (2002-03-03) * First release _________________________________________________________________ Copyright (c) 2002-2018 proconX Pty Ltd.
