Table 3-4. Datacomm Configuration Menu Fields (Continued)
This field specifies whether or not a true (most positive volt-
age) state on the Secondary Receiver Ready (SRR) (Data Car-
rier Detect (CF)) control line is a required condition for
receiving data.
Values:
Yes
No
Default = No
Transmit pacing is a mechanism by which the remote device
can control (stop and resume) the transmission of data from
the terminal.
If enabled, transmit pacing is performed using XON and
XOFF control codes. When the terminal receives an XOFF
(ASCII <DC3», it stops transmitting data. When the termi-
nal subsequently receives an XON code (ASCII <DC1 », it
resumes transmitting data. Note that when transmit pacing
is enabled, it may interfere with the operation of DCI/DC2
pacing as specified by the InhHndShk<G> and InhDC2<H> on
the Terminal Configuration menu. If
XON/XOFF
transmit
pacing is enabled, DCI is treated as an XON only when a
previous DC3 (XOFF) has been received. Also, the DCI char-
acter is used for both XON and the handshake trigger, so the
host program must take care to distinguish between the two.
If this field is set to ((Hone", the terminal does not recognize the
ASCII <DC1 > and <DC3> codes as XON and XOFF.
For other forms of transmit pacing, refer to the description of
the ((SRRXmi t", ((CS<CB>Xmi t", and ((DM<CC> Xmi t" fields.
Values:
None
Xon/Xoff
Default=None
This field specifies the group identification code to be used by
the host computer for selecting individual terminals.
((Selecting" is the mechanism the host computer uses to trans-
mit data to a terminal.
