There was a posting here about use of the USB DEC Express with speakup--a configuration I thought to be impossible. I assume that it is done using a USB serial port driver appropriate to the USB to RS232 interface used on the units, much as we do with USB GPS devices? Does anyone care to comment on this? As a side note: has anyone managed to get the same theory to work for the Trippletalk USB, or is that a different animal? Thanks Luke
