DN(4)               UNIX Programmer's Manual                DN(4)

NAME
     dn - DN-11 ACU interface

DESCRIPTION
     The files _c_u_a_0, etc. refer to the units of a DN-11 ACU
     interface, and are write-only.  The codes for the phone
     numbers are:

     0-9  dial 0-9
     :    dial *
     ;    dial #
     -    2 second delay for second dial tone
     <    end-of-number

     It is recommended that an end of number code be given even
     though not all ACU's actually require it.
