Chapter 3. Keys and messages
When you press this key in character or echo mode, the display station
transmits only the AI D code and a turnaround character to the host.
When you press this key in block mode, data transmission depends on the
Send Data Format option. When you press this key in an unformatted page,
the current line data is transmitted to the host. If you press this key in a
formatted page, the volume and type of data transmitted (modified data only
or unprotected data only) will depend on the field data transmission mode set
by the host. See Chapter 5, "Commands and responses" for details.

Sends data to the host system, depending on the operating mode
and options
The function of this key depends on the operating mode of your display
station.
In character or echo mode, the display station transmits only the AI D code
and a turnaround character to the host.
In block mode, the type of data transmission depends on the Send Data
Format option. This key causes the display station to transfer data in the same
way as the Pr Msg key, but to the host instead of the printer.
,boJter data transmission, the cursor moves as follows:
• If the Lock KB D and Keep MDT option is off, the cursor moves to the first
character position of the next line. In addition, the affected MDT bit is
automatically reset to O.
• If the Lock KB D and Keep MDT option is on, the keyboard is locked and
the cursor does not move until the Reset KB D and MDT command is
received. When the Reset KBD and MDT command is received, the
keyboard is unlocked and the cursor moves to the first character position
of the next line. In addition, the affected MDT bit is automatically reset to
O.
If you press this key in a formatted page, the volume and type of data
transmitted (modified data only or unprotected data only) will depend on the
field data transmission mode set by the host. See Chapter 5, "Commands
and responses" for details.
