Note: This menu uses “string entry” parameters. For detailed information
about entering data in this type of parameter, refer to “String Entry
Parameters” on page 115.
In
This parameter enables the serial port input fields. If enabled (set to “Y”), the TESS
application has exclusive use of the serial port. Data entered in these fields must
begin with a SI Prefix and end with a SI Suffix character.
Exclusive
TESS sessions can be configured to receive all serial input, even if they are not the
currently active session. To send data to a single session, the ‘Exclusive’ parameter
must be set to ‘Y’. If more than one session has the ‘Exclusive’ parameter enabled,
the session with the largest application number (1-4) receives the serial input. The
other(s) do not see any serial input.
SI Mode
TESS supports communication to and from the terminal serial port using two
methods:
Command and Field. When SI Mode is set to field, serial input is
displayed in serial-input fields and serial output is displayed in serial-output fields
on the current TESS page. The serial input fields are defined in the System Network
Controller configuration (see ‘9300 Network Controller User Manual” – PN 80409
and “Teklogix Screen Subsystem (TESS) Programmer’s Manual” – PN 79186 to
review TESS field extended attributes and the bits ‘b’ command).
The data is sent to
the host as field data. Serial output with controller emulations is provided through
the passthru-printing feature.
