I think it should be possible to directly read/write the device, perhaps after
calling 'stty' to set parameters

   (err "/dev/null"  # stty arguments depend on your situation
      (call "stty" "/dev/ttyACM0" "raw" "-echo" "-echoe" "-echok") )


   (out "/dev/ttyACM0"
       ... )

   (in "/dev/ttyACM0"
       ... )

Use 'char' or 'line' to read text, or 'rd' to read binary data, and 'prin' or
'prinl' to write text, or 'wr' to write bytes.
