Communications Blockset Release Notes    

Block Name Changes Since Previous Manual

The table below lists the old and new names of blocks that were part of the Communications Toolbox before Release 12 and that have changed their names. The old names are from the last printed version of the Communications Toolbox User's Guide. Because the libraries have been reorganized since that document was printed, the third column of the table lists the current library name for each block.
