RemoveConnection accepts one optional argument.
filename = string
used to specify the file from which this connection is removed. When no filename is given, connections will be loaded from "$HOME/maple/toolbox/Database/data/default.con", where $HOME is the value returned by kernelopts( homedir ).
Create a connection.
