Jordan K. Hubbard 1d8812734b I have applied my last changes correcting the bug in dgbselect() to it 
and here is the patch.  Submit it please. Thank you!

BTW, there is a new option "NDGBPORTS". By default it is equal to
NDGB*16 and means the number of ports of all Digiboards for which the
tty structures are reserved. It can be set to the real value in config-file
like:

       options "NDGBPORTS=8"
