17. Attempt an Apple Boot over LocalTalk I/F 1. If successful,
goto 24.
18. Attempt an Apple Boot over LocalTalk I/F 2. If successful,
goto 24.
19. Attempt an Apple Boot over LocalTalk I/F 3. If successful,
goto 24.
20. If MOPboot is not enabled, goto 22.
21. Attempt MOPboot. If successful, goto 24.
22 If a serial cable is connected, and a ^C or DEL
character has been received, goto 25.
23. Goto 9.
24. Run the loaded gateway code. If a "q" command is received,
goto 25.
25. Display the "LT>" prompt. Wait for commands.
For a Factory-Configured MultiPort/LT, the IP address is not configured. As a
consequence of the above sequence, if the MultiPort/LT has been powered-on
without a "live" serial cable attached ("live" meaning with MGTalk), then it will
not display the "LT>" prompt when a cable is connected unless it receives ^C
(Control-C) or DEL (delete-key - not backspace).
2.1.6
MultiPort/LT IPTalk Operation
2.1.6.1. Definition of IPTalk
Under Apple's terminology "XxxxTalk" means that the AppleTalk data packets
are being "Transported" over or delivered by an "Xxxx" network. For
example:
Protocol
AppleTalk packets are transported over:
LocalTalk
Apple's LocalTalk network wiring
EtherTalk
Ethernet
TokenTalk Token Ring
IPTalk
An IP-protocol-based Network
IPTalk is the odd one out here. The other three are transporting AppleTalk
packets directly over a "raw" network. With IPTalk, AppleTalk packets are
being encapsulated inside another networking protocol - IP (which is the lower-
level part of TCP/IP).
This means that AppleTalk packets can travel over almost any existing IP
network, no matter what underlying transport hardware is used to guarantee
delivery of the IP packets.
