|stemRef||-||A pointer to the opaque stem reference used for sending the packet.|
|nAddress||-||The address of the module that will be connected to the stream.|
|pStreamRef||-||A pointer to the aStreamRef that will be filled in by this routine for communicating with the requested module's serial port.|
|pErr||-||A pointer to an aErr variable that recieves the error code on exit from this routine.|
The streams created by this routine are valid as long as the aStem library has not been destroyed. When it is destroyed using the aStem_ReleaseLibRef routine, any outstanding relay streams become invalid and subsequent operations on them will return an error.
