null characters to wait before continuing to
send any other characters.
-There are no real characters sent. The
APM/SPM waits the amount of time it would
take to transmit those characters.

0 for hostl-255 = number of characters per line
-This parameter specifies the default value of
line folding.
-This parameter determines the number of
characters to transmit before an automatic
carriage return/line feed is sent. This causes
long lines to fold or wrap onto the next line.
-If this parameter is 0, the function is
disabled. A backspace will cause the internal
counter to be decremented by one for each
backspace character received. A carriage
return will reset the counter.
-This parameter is normally set at 0 since
most station equipment performs this function
automatically. Otherwise, standard line
lengths are 80 or 132 characters.
-This is X.3 parameter 10.

-This will disallow transmission of control-S
and control-Q. However, if this parameter is
disabled (N), the device cannot flow control
the PAD, but the device can transmit the flow
control characters through the network.
-Control-S stops the PAD and control-Q
ends flow control. This is commonly done by
printers and users that get behind in some
type of listing and wish to catch up.

parameter is enabled, the PAD will process
editing characters. This only applies to data
transfer mode. Editing will always be enabled
(Y) for command mode on terminals. If this
field is enabled, timers should be turned off
and the forwarding condition should be set to
transmit on carriage return. If this field is
disabled (N), all editing characters (LF, BS,
etc.) are lost in data transfer mode.

N for hosthook) and the time when the connection is
actually dropped.
-If Y is selected (enable), mark Record
Code Cl, columns 46-48, with the actual
delay time.
-This configuration parameter determines
whether or not the port is configured to use
the DSS wait-down option.
-This option specifies the use of the
disconnect delay timer.
-This timer comes into effect any time the
PAD disconnects the device (terminal or
host). When a PAD drops its DSS, it begins
running this timer. When the timer expires,
the PAD can continue on to its next DSS
state.-This parameter specifies whether or not
this timer value can be used.
=lf this field is enabled, the PAD will use the
timer that is defined on Record Code AP,
columns 24-26, for 
APMs or XP, columns
60-62, for 
SPMs; otherwise, no timer will be
run. This allows hosts that do not scan their
DSS very quickly to catch ports that were
remotely disconnected.
