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
