   First question is this; with the release of 0.99pl5 today there is a new
   device for the serial lines. They, the cu devices, are major 5 and the same
   minor numbers. My question is, what does this do to /dev/tty? I have this
   as device 5 0. Is this obsolete or what?

/dev/tty is still 5 0. The minor device numbers for /dev/cuaXX start at
64, just like the minor device numbers for /dev/ttySXX.

   Does anyone have a script or program that updates the dev directory? If not
   and anyone knows what devices are current, I will try to write such an
   updating program.

There is such a program, MAKEDEV, in /dev in the SLS distribution.
However, it needs to be updated to deal with the new callout device, to
and to accept serial ports as high as 63 (i.e., /dev/ttyS63).
