+** HostUniqueNum is the unique number from the host card that this RTA
+** is to be connected to.
+** RtaUniqueNum is the unique number of the RTA concerned. It will be ZERO
+** if the slot in the table is unused. If it is the same as the HostUniqueNum
+** then this slot represents a host card.
+** Flags contains current boot/route state info
+** SysPort is a value in the range 0-504, being the number of the first tty
+** on this RTA. Each RTA supports 8 ports. The SysPort value must be modulo 8.
+** SysPort 0-127 correspond to /dev/ttyr001 to /dev/ttyr128, with minor
+** numbers 0-127. SysPort 128-255 correspond to /dev/ttyr129 to /dev/ttyr256,
+** again with minor numbers 0-127, and so on for SysPorts 256-383 and 384-511
+** ID will be in the range 0-16 for a `known' RTA. ID will be 0xFFFF for an
+** unused slot/unknown ID etc.
+** The Topology array contains the ID of the unit connected to each of the
+** four links on this unit. The entry will be 0xFFFF if NOTHING is connected
+** to the link, or will be 0xFF00 if an UNKNOWN unit is connected to the link.
+** The Name field is a null-terminated string, upto 31 characters, containing
+** the 'cute' name that the sysadmin/users know the RTA by. It is permissible
+** for this string to contain any character in the range \040 to \176 inclusive.
+** In particular, ctrl sequences and DEL (0x7F, \177) are not allowed. The
+** special character '%' IS allowable, and needs no special action.
