SENDING
Data
entered while
the
terminal
is in
BLOCK mode
is not
transmitted
to the
host
until
you
SEND
it.
(NOTE:
If the
terminal
is not in
BLOCK mode
and you try to
SEND, only
the
particular escape sequence
is
sent.)
There
are
nine commands which
can be
used
to
transmit data from
the
terminal
to the
host.
Table
3-10
indicates
the
code used
to
initiate transmission
and if the
SEND
key can be
used
to
initiate transmission. Table 3-11 describes
the
effect
of
each command
if the
terminal
is
set
to
Protect
(Text)
mode
(PRTon
Status Line).
NOTE: When attempting
to
send only unprotected characters, make sure that Protect
Mode
is on:
It's
ON if
"PRT"
appears
on the
Status Line.
NOTE
If
the
terminal
is set to
PROT OFF,
SEND-unprotected
commands work
like
SEND-all
commands: they transmit
all
characters
(in
particular,
no
start
or end of
unprotected field codes
are
sent).

3-10.
