Double Talk LT, but no serial port. Where do we go from here?

Hi Mike.  Speakup does not support usb devices..  Therefore, you can
either use one of the supported software synthesizers, several of which
are free, or you can purchase a pcmcia serial card.  To use this with
the doubletalk lt, you will have to specify none as the default
synthesizer, and then specify the ltlk driver after the pcmcia devices
have been initialized.  Hope this helps.
