SSMKN(8)		  BSD System Manager's Manual		      SSMKN(8)

NAME
     ssmkn - Equinox SuperSerial Technology device configuration utility

SYNOPSIS
     /usr/sbin/ssmkn

DESCRIPTION
     In a system with more than one adapter card installed, a logical adapter
     card number must be mapped to each physical adapter card. These logical
     adapter card numbers are assigned sequentially in ascending order start-
     ing with the lowest slot (for PCI, EISA, or Micro Channel systems) number
     followed by  I/O address sequence (for ISA) adapter cards. A problem ex-
     ists in a two adapter card system if the first logical adapter card is
     removed, the ports	 that were 2a0, 2a1, 2a2 etc.  would become 1a0, 1a1,
     1a2 etc. This presents a potential security problem as well as a configu-
     ration issue because any modems or printers defined on adapter card two
     would no longer function. More adapter cards magnify the problem. To
     overcome this problem, Equinox installs a program (/usr/sbin/ssmkn) that
     maintains a database mapping of logical adapter card numbers to physical
     adapter cards.

     The following section lists the rules that are used to maintain this map.
     Messages are generated when an adapter card is added to, relocated within
     or removed from the system.

     Every time the system is booted, the program ssmkn checks to see if any
     adapter cards were added to, relocated within or removed from the system.
     The program decides if map changes are required.  The rules for mapping
     logical adapter card numbers to physical adapter cards are applied in the
     order numbered below. If two or more rules apply, the lowest numbered
     rule takes effect.

     1.	     Adapter card type, bus type and location match.
	     If the adapter card type, bus type and location (slot or I/O
	     address) match, it is assumed that the same adapter card is
	     present that was previously installed. No changes are made to the
	     stored (logical adapter card number to physical adapter card)
	     map. This occurs normally each time the system is booted if no
	     SST adapter cards were added, removed or moved to a different
	     slot.

     2.	     Adapter card type and bus type match.  Location does not match.
	     If the adapter card type and bus type match but the location
	     (EISA slot or ISA I/O address) of the adapter card changes, the
	     adapter card maintains the same logical number previously
	     assigned (e.g.,  an EISA adapter card is relocated into a
	     different slot)

     3.	     Location matches, adapter card type and/or bus type do no match.
	     Any adapter card now appearing in a previously occupied PCI,
     EISA,
	     or Micro Channel slot (or ISA I/O address) is considered a
	     replacement. This adapter card is given the logical adapter card
	     number of the previous adapter card.  For example, this would
	     occur if you replaced a SST-4 adapter card with a SST-8
	     adapter card.

     4.	     Nothing matches.
      a.     When the same number of adapter cards expected to be found
	     (logically) are found (physically), but the bus type or
	     "location" is different, each adapter card is considered to be
	     a replacement. The adapter cards are mapped in "location" order.
	     This would occur if you replaced two SST ISA adapter cards with
	     two SST EISA adapter cards.
      b.     If the physical number of adapter cards found is less than the
	     number of adapter cards expected, and the bus type or "location"
	     is different, the adapter cards are mapped as in 4.a. above.
	     The program reports any remaining adapter cards as missing.  For
	     example, this could happen if you replaced three ISA adapter
	     cards with two EISA  adapter cards.
      c.     If the physical number of adapter cards found is greater than the
	     number of adapter cards expected, and the bus type or "location"
	     is different, the adapter cards are mapped as in 4.a. above.
	     The program reports any additional adapter cards as new.
	     This may occur if you replaced two ISA adapter cards with three
	     EISA adapter cards.

CONFIG
     Port names are of the general form /dev/tty<adapter card><module><port>

     <adapter card> - is a single number between 1 and 8.
		      The adapter card numbers are assigned in slot order
		      for PCI and EISA systems. They are assigned in I/O ad-
     dress
		      sequence for ISA systems.

     <module>  -   is a lowercase letter from a through h, representing the
		   first module (PM-8, PM-16 or MIM-1) through the eighth
		   module of a SST subsystem.

     <port> - is a hexadecimal number from 0 to f.  The <port>	number is the
	      actual port number on a SST-64 or SST-128 port module, or SST-4
	      or SST-8 fan-out cable.

CONFIGURATION
	 The following example is added to the file /etc/rc.local

	  /usr/sbin/ssmkn
