                     12: The COHERENT  system is a  multiuser operating system;  it allows
                     13: many  users to  use the  system simultaneously.   An asynchronous
                     14: communication port connects  each user to the system, normally by
                     15: a  terminal or  a modem  attached to the  port.  The  system com-
                     16: municates with  the port by means of a  character special file in
                     17: directory /dev, such as /ddeevv/ccoomm33rr or /ddeevv/ccoomm22ll.
                     18: 
                     19: The COHERENT system will not allow a user to log in on a port un-
                     20: til the system creates a  login process for the port.  The enable
                     21: command tells the system to create a login process for each given
                     22: port.  For example, the command
                     23: 
                     24: 
                     25:         /etc/enable com1r

                     27: 
                     28: enables port /dev/com1r.
                     29: 
                     30: enable  changes the  entry for  each given  port in  the terminal
                     31: characteristics  file  /etc/ttys.   The  baud rate  specified  in
                     32: /etc/ttys must  be the appropriate baud rate  for the terminal or
                     33: modem connected to the port.   See the Lexicon entry for ttys for
                     34: more information.
                     35: 
                     36: The command disable  disables a port.  The command ttystat checks
                     37: whether a port is enabled or disabled.

                     50: enable normally  returns one if it  enables the port successfully
                     51: and  zero if  not.  If  more than one  port is  specified, enable
                     52: returns the success or failure  status of the last port it finds.
                     53: It returns -1  if it cannot find any given  port.  An exit status
                     54: of -2 indicates an error.

                     57: 
                     58: It is not  recommended that you attempt to enable  a port that is
                     59: already enabled.   To make sure, run  /etc/disable before running
                     60: /etc/enable.
