	 Hello Net People:

                 In  Gary  Falsken  of  Renaissance  Consulting's
         article  he states that they have a problem with a hayes
         1200 and an AT&T 3B2.  We have an AT&T  3B2/300  with  a
         hayes  1200.   We  too  had  this problem.  We are using
         AT&T's  Basic  Networking  Utilities.   Our   modem   is
         connected  to  the  contty  port.   One  might  try  the
         following entries in their /etc/inittab file:

         TO ANSWER:

         	##:2:respawn:/etc/getty -t 60 tty## 1200

	 TO DIAL:

	 	ct:2:off:/etc/getty -t 60 contty 1200

		 Where ## is the number of the tty.

                 With the combination of an AT&T 3B and  a  hayes
         1200  (to  the  best  of  knowledge) one can not set the
         modem bidirectional.  I  have  never  received  a  valid
         reason  for  this.  The switch settings for the hayes is
         as follows:

         TO ANSWER:      TO DIAL:
         1 3 5 7 90      12 4  7 90
         ----------      ----------
          2 4 6 8          3 56 8
