an address character other than

This option permits the
CPU to broadcast to two or more
Display Terminals simultaneously.
Frame Reset at End
The cursor is frame reset at the
of Transmit

of being advanced to the first
character position of the next line.

Two options are available:
End-of-Transmis sion
Character
Advance Line After Receive
Nonblinking Cursor

Depressing the END key inserts
an ETX code, then frame
resets the cursor and raises
the Request-to-Send line.
2)
Depre s sing the END key
inserts an ETX code and
then moves the cursor to the
fir st character position of
the line it is on and initiate s
automatic transmission to
the ETX.
An EOT character code (0000100)·
is substituted for the ETX
character code (0000011).
This

polling sites where EOT signifies
the end of transmission from the
site.
When an ETX character is decoded
in a received message, the cursor
is automatically advanced to the
first character position of the
next line.
A nonblinking cursor in the form of
a backward L
(J )
may be displayed
rather than the standard DIDS-400
blinking cur s or
