Block Data Transfer
SEND DISPLAY (Ec d)
From a program executing in a host computer, you can trigger a block transfer of data from the
workspace to the host computer by issuing the following escape sequence:
Ec d
This escape sequence is only responded to when received over a datacomm line; it is ignored if
entered through tJ:1e keyboard or issued from a user key (unless Block mode is enabled). With
the following exceptions, the resultant data transfer is performed as though the. key had
been pressed:
1. The cursor is not repositioned. The data transfer always begins at the current cursor
position.
2. A non-displaying terminator is never inserted at the cursor position as part of the operation
(the
AutoTerm(J)
configuration parameter is ignored).
The
((Ec d"
sequence also temporarily disables the keyboard so that the. key cannot be used
until the current data transfer is completed. If the
((Ec d"
sequence is received while an. key
data transfer is in progress, the escape sequence is ignored.
Note that an
«Ec
d"
sequence resets the ((block trigger received" flag. This means, for example,
that if you are using the DCI handshake and the terminal receives a <DCI> followed by the
((Ec
d",
it ((forgets" that a block trigger (the <DCI» was just received and thus will not send
the data immediately. The terminal must receive another <DCI> before it will start the data
transfer.
TRANSMIT-TYPE FUNCTION KEY DEFINITION STRING TRANSFER
If a function key of Transmit type is pressed in Remote mode, its definition string will be
transmitted to the host computer, as a block. It can also be transmitted using the following
escape sequence:
Ec &f <x>E
where
((x"
is the identification number
(1-8)
of the function key.
When in Block Page mode, the end character is the configured block terminator; otherwise the
ending is CR (LF).
USER KEY DEFINITION STRING TRANSFER
When the User Key menu is displayed and the terminal is in Remote mode, both the. key and
((Ec d"
sequence cause one or more of the function key definitions to be transmitted, in the
escape sequence form. The
Au t oTerm( J)
and
Cl earTerm(K)
entries on the Terminal Configu-
ration menu are ignored under these circumstances.
