Have you considered soundcard modem for that? Just use something like a Buxcomm Rascal or a Signalink as the interface and run cables in/out of the soundcard on the laptop.
Already use mixw for most digital modes. It's really difficult, if not impractical to do pactor / amtor ARQ modes without a TNC. I need to use those specific modes.
