convert to support non-dma IO (for the isa Riscom/N2). allow the user to set and use the internal baud rate generator fix the transmission ring logic to support more than 1 frame per interrupt add autodetection of the base clock frequency. cleanup the receive ring logic support dynamically resizing the low-water mark on the fifo in response to buffer underruns on transmit.
