Table 7-4. Point-to-Point Configuration Menu Fields (Continued)
This field specifies
whether
or
not
a true state
(-12
V)
on the RS-232C Receiver Ready (RR)
or
Data
Carrier Detect
(CF)
control
line is a required condition
for
receiving data.
Values: YES
NO
This field specifies
whether
or
not
a true state
(-12
V)
on
the
RS-232C Clear
to
Send (CstCS)
control line
is a required condition
for
transmitting data. For a modem configuration
it
is set
to
"YES".
Also,
if
the
A!lt"ri!lk
field is set
to
"cs",
then
CS(CB)Xm1
t should be set
to
"YES".
Values: YES
NO
This field specifies
whether
or not the terminal should automatically switch from receive mode to
transmit mode when the state
of
the RS-232C Receiver Ready (RR)
or
Data Carrier Detect (CF)
control line
changes from true (HI) to false (LO).
Values:
YES
NO
If half duplex Main Channel protocol is being used, this field specifies whether
or
not
a Start-
Of-Data control
character will be used. If this field is set
to"
YES",
then the specified Start-Of-Data
control
character will be used. If this field is set
to"
YES",
then the specified Start-Of-Data control
character (see the XmitSOD and RecvSOD fields below) will automatically
be
supplied by the
terminal at the beginning
of
all transmitted text blocks and be required at the beginning
of
all
received text blocks.
Values:
YES
NO
If
half
duplex
Main
Channel
protocol
is
being
used
and
the
SOD?
field
is
set
to
"YES",
this field defines the Start-Of-Data control character that the terminal will use when
transmitting data
(normally
an
ASCII
<STX».
Note that you must enable display functions mode
to
enter an ASCII control code into this field.
If
h&:~
duplex Main Channel protocol is being used and
the
SOD? field is set
to
"YES",
this field
defines the Start-Of-Data control character that the terminal will be looking
for
when receiving
data
(normally an ASCII
<STX».
Note that you must enable display functions mode
to
enter
an
ASCII control code
into
this field.
If half duplex
Main Channel protocol is being used, this field defines the End-Of-Data control
character that
the
terminal will use when transmitting data (normally an ASCII
<ETX».
Note that
you must
enable display functions mode
to
enter an ASCII control code into this field.
If half duplex
Main Channel protocol is being used, this field defines the End-Of-Data control
character that the terminal will be looking
for
when receiving data (normally
an
ASCII
<ETX».
Note
that you must
enable display functions mode
to
enter
an
ASCII control code into this field.
If
this field is set
to
"YES",
a transition from true (HI)
to
false (LO) on the RS-232C Secondary
Receiver Ready
(SRR)
or
Secondary Carrier Detect (SCF) control line will cause the terminal to
switch from transmit mode
to
receive mode.
Values:
YES
NO
For half duplex
protocols
this
field specifies whether or
not
you want circuit assurance
..
1f
circuit
assurance is
enabled,
the
RS-232C Secondary Receiver Ready (SRR) or Secondary Carrier Detect
(SCF) control line must be true (HI) in order for the terminal
to
be
able
to
switch from receive mode
to
transmit mode. Note
that
if
CircAssr=YES, then the SwitchSRR field must also be set
to
"YES".
Values:
YES
NO
This field specifies whether the terminal should be initialized in transmit mode or receive mode.
Values: XMIT
RECV
