DN(IV)                       8/24/73                       DN(IV)







NAME

     dn - dn11 ACU interface



DESCRIPTION

     The dn?  files are write-only.  The permissible codes are:



         0-9  dial 0-9

         :    dial *

         ;    dial #

         =    end-of-number



     The entire telephone number must be presented  in  a  single

     write system call.



     It is recommended that an end-of-number code be  given  even

     though only one of the ACU's (113C) actually requires it.



FILES

     /dev/dn0        connected to 801 with dp0

BUGS

     It needs a delay character to handle second dial tone.
