I had received a patch tape from sun to try and fix this and several other
problems with the ALM-2 board.  Speaking with a Sun Techie (yes, I
actually got a response!!!!), he informed me that:

1.)  serial lines were one of the many hangups in the late release of 4.0.1.
     The more the fixed them, the worse other problems got.  They finally
     released 4.0.1, but without this being fixed!
2.)  sometime in the near (distant?) future, ANOTHER patch tape will be 
     released with some more of the tty and serial bugs fixed.

Sun strikes again . . .
