Table 7-4. Point-to-Point Configuration Menu Fields (Continued)
This field specifies the number of "stop bits" you wish appended to each data character
transmitted by the terminal (received data is accepted with one or more stop bits regardless of the
setting of this field).
Values:
1.5
2
This field specifies whether the data com m clock source is to be generated by the terminal or by the
external device. If an external clock source is selected, this field also specifies what multiplication
factor is to be used for synchronizing with the external clock source.
Values:
IHT
EXT X1
EXTX16
The HP 264x family of terminals all have a TRANSMIT indicator (LED): On the HP 2624A, an asterisk
below the current row/column numbers atthe bottom line on the screen serves this function. When
the asterisk is present, the TRANSMIT indicator is on; when the asterisk is missing, the TRANSMIT
indicator is off.
This field specifies whether the transmit indicator should be enabled or disabled and, if enabled,
which RS-232C control line it should reflect.
The value
"OFF"
disables the TRANSMIT indicator altogether. The value
"CS"
specifies that the
TRANSMIT indicator should reflect the state of the RS-232C Clear to Send (CS) control line
(asterisk=HI; no asteris·k=LO). The value "OM" specifies that the TRANSMIT indicator should
reflect the state of the RS-232C Data Mode (OM) or Data Set Ready (CC) control line (asterisk=HI; no
asterisk=LO).
Values:
OFF
CS
OM
This field enables or disables the use of the Hewlett-Packard
EHQ-ACK
handshake. This type of
handshaking is described under "Pacing Mechanisms" in the "Point-to-Point Programming
Information" portion of this section.
Values:
YES
HO
(enable)
(disable)
This field specifies whether all
<HULL>
and
<DEL>
codes are to be deleted from the input data stream
without being processed. With 7-bit data the codes are hexadecimal 0 and 7F, respectively, and
with a-bit data they are 0 and FF.
Values:
YES
(delete NULLs and DELs)
HO (treat NULLs and DELs as data)
The default value for this field is
"YES".
In most point-to-point data comm configurations you will
typically want NULL and DEL codes deleted.
This field specifies the desired state of the RS-232C SR line when the terminal's power is first
turned on or when the terminal is reset. The SR line, RS-232C pin number 23 of the HP 13222/13242
C, M, and N cables, is defined as the Data Signal Rate Detector (DTE Source). It is normally used on
dual speed modems to select the appropriate speed (single speed modems merely ignore this line).
Values:
HI
LO
This field specifies the desired state of the RS-232C TR line when the terminal's power is first
turned on orwhen the terminal is reset. The TR line, RS-232C pin number 20 of the HP 13222/13242
C, M, and N cables, is defined as Data Terminal Ready. Whenever the terminal performs a
disconnect, it also returns the TR line to the state specified by this field.
Values:
HI
LO
