Configuring the Terminal
Table 3-4. Datacomm Configuration Menu Fields (Continued)
If this field is set to ttXonXoff", the terminal will automati-
cally perform receive pacing using XON (ASCII <DC1 » and
XOFF (ASCII <DC3» control codes. With this type of receive
pacing, the terminal causes the remote device to halt trans-
mission by sending an XOFF code and to resume transmission
by sending an XON code. For this type of receive pacing to
work, the remote device must of course be configured to start
and stop transmission in response to XON and XOFF codes.
Note that if the remote device recognizes XON and XOFF
codes and your terminal is operating in Character mode, you
can issue the codes through the keyboard regardless of the
setting of this field. The •
and
Q
(or q) keys (when pressed
simultaneously) generate an XON code and the •
and S (or
s) keys generate an XOFF.
If this field is set to ttTR( CD>", data receipt is controlled by the
state of the Data Terminal Ready signal line (refer to TR( CD».
When, while receiving, the terminal reaches a state in which
it can no longer receive, it deactivates the TR line to stop the
transmitter from transmitting. Then, when it is ready to
receive, it reactivates the TR signal line.
Values:
None (default)
XON/XOFF
TR(CD> (Full Duplex Hardwired only)

None
This field specifies the group identification code to be used by
the host computer for polling individual terminals. ttPolling"
is the mechanism the host computer uses to allow a terminal
to transmit data.
The group ID for polling may be any of the following ASCII
characters, the only limitation being that it must be a differ-
ent character than the one used for the group ID for selecting
(see SGroup
ID):
