(terminal will

No handshake.
Specifically, however,
the
type
of
handshaking
used
for
block
transfers
is
determined
by a
combination
of
the
following
factors:
1.
The
type
of
block
transfer
to
be
performed.
2.
What mode
the
terminal
is
currently
operating
in (character,
block
line,
block
page, or
modify
mode).
3.
The setting
of
the
inhHndShk(G) and
inh
DC2{H} fields.
If
your
terminal is
connected
to
a Hewlett-Packard
computer
system, you will
find
that
the
default
settings
for
these
fields
(both
OFF) are usually adequate
for
your
purposes. If you are
concerned
about
the
specific
type
of
handshake
to
be used
for
one
or
more
of
the
particular
types
of
block
transfers, however, you
should
