using schema.ini files with DoCmd.TransferText

[Guest_imported]

Does anybody know how to use a schema.ini file in place of an import specification?
I've tried the obvious options, and nothing seems to work.

DoCmd.TransferText TransferType:=acImportDelim SpecificationName:= ?????

I have a schema.ini file stored in the directory with the file I want to import, which is what the help file says to do. Yet it doesnt work.

Thanks
