Teklogix 9150 Wireless Gateway User Manual
The 9150 displays this version of the Emulation Options page after you have
selected the 5250/Telnet emulation/protocol combination for this host connection.
With IBM 5250, or IBM 3274 emulation, the 9150 mini-controller converts the
application data stream from the host to TESS (Teklogix Screen Subsystem)
commands. Some of the parameters in this page govern the conversion of the host
screens to TESS.
Write Error Code
If advisory text is selected here, the 9150 sends error codes to the terminal screen as
advisory text, which is written at the bottom of the screen. If screen text is chosen,
the 9150 sends the error codes as regular screen text.
Use International EBCDIC
If this parameter is enabled, the 9150 will swap the positions of the ! and ] charac-
ters in the EBCDIC character table.
Alarm
If this parameter is enabled, terminals will beep when the word “ALARM”
(in capital letters) appears on the application screen, in the location specified by the
Command Region parameter (see page 175). The word “ALARM” should be a
display-only field.
Note: The Command Region parameter must be enabled for this
parameter to work.
Clear
If this parameter is enabled, the 9150 mini-controller creates an empty entry field
for an entry field that is filled with spaces.
Some host applications rely on the video attributes of displayed characters to high-
light fields, particularly entry fields. For example, the application screen may define
all entry fields with reverse video and fill the field with spaces. This is effective on
terminals that support reverse video, but on terminals that do not, it can make the
field invisible since it is made up entirely of spaces.
