ports(8)              MAINTENANCE COMMANDS               ports(8)



NAME
     ports - create character device files  and  inittab  entries
     for ports boards

SYNOPSIS
     /sbin/ports

DESCRIPTION
     The ports command creates character device files in /dev and
     adds  new entries in /sbin/inittab for 4 asynchronous RS-232
     ports and 1 parallel printer port.  A port is  named  ttysn,
     where s is the slot number and n is a number from 1 to 5.

     If the board configuration has changed, ports does the  fol-
     lowing:

          Remove any tty device files for a board that no  longer
          resides in a slot.

          Remove device files of other boards such as the NI if a
          ports  board  now  resides  in the slot that previously
          held an NI.  A message warning that a  device  file  is
          being removed is sent to the console.

          Make new tty device  files  for  the  ports  boards  if
          needed.

          Make new inittab entries for the ports boards.

     If the configuration has  not  changed,  the  ports  program
     exits without doing anything.

     Any devices, such as a printer or a modem, that are added to
     a  ports board should link the names that are to be used for
     the devices to the corresponding tty device files that  were
     created  [see  ln(1)].   The command can be used only by the
     super-user.

EXAMPLE
     A parallel printer is added to a ports board that is in slot
     1.  The corresponding slot is tty15.  The user should use ln
     to link an appropriate name such as lp1 to  the  tty  device
     file.
          ln /dev/tty15 /dev/lp1

FILES
     /sbin/inittab
     /dev/ttysn

NOTES
     A warning is issued for each device  file  that  is  removed
     provided  it is not a tty device file.  If a ports board has
     been removed and lp1 has been linked to a tty  device  file,
     the message is as follows:
          Warning: /dev/lp1 is being removed.
