non-blocking tty

[Jim Gottlieb]

Recently, someone suggested that by doing a 'mknod ttyd0 c 0 128' you
would create a descriptor for the same line as tty000, except that it
would not be necessary to hold CD high to communicate with the port.

Was anyone able to get this to work?  I did this, but found that my new
port also needed CD high to connect to it.

If not, it may be time to get out the soldering iron and tie the
TrailBlazer's DSR to the 3B1's CD.
