SAPConsole not working after SAPGui 6.40 upgrade (I/O engine

For the SAPConsole 6.20 version, we had customized the I/O Engine

(sapVTIO) per SAP documentation to enable interoperability with other

software components.

After upgrading to SAPGui 6.40, we came to realize that the SAPConsole

seems to no longer use the I/O Engine and our custom version of sapVTIO

does not get invoked. There seems to be no place in the SAPConsole

administrator for specifying the I/O engine.

How do we specify the I/O Engine for SAPConsole 6.40?
