HELLO_REPLY FIELDS:
LDP Version
The target's LDP protocol version. If the current
host protocol version does not agree with the target's
protocol version, the host may terminate the session, or
may continue it, at the discretion of the implementor. The
current version number is 2.
System Type
The type of system running on the target. This is used as a
check against what the host thinks the target is. The host
is expected to have a table of target system types with
information about target address spaces, target-specific
commands and addressing modes, and so forth.
Currently defined system types are shown in Figure 15. This
list includes some systems normally thought of as 'hosts'
(e.g. C70, VAX), for implementations where targets actively
initiate and direct a load of themselves.
