Chapter 23: Mini-Controller Configuration
5250 Emulation
Clear
If this parameter is enabled, the 9160 G2 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 highlight
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 mobile computers
that support reverse video, but on mobile computers that do not, it can make the field invisi-
ble since it is made up entirely of spaces.
By default, all empty entry fields displayed at the Psion Teklogix mobile computer are high-
lighted by the "entry character" chosen in the mobile computer's configuration. The Clear
feature creates an empty entry field in place of an entry field filled with spaces.
Note: This operation is only performed on screens received from the host. Data sent to the
host remains unaffected.
Passthru
If this parameter is enabled, the 9160 G2 allows the host to send data directly to the RF
mobile computer's serial port. This is most commonly used for printing.
Preparing Host Screens for Pass-Through
On the screen to be sent through the mobile computer serial port, the word "PASSTHRU"
(in capital letters) must appear on the first line, starting on the second column. The actual
data to be sent to the mobile computer may start anywhere below the first line.
With 5250 or 3274 emulations, attributes occupy a position in the screen buffer. An attribute
placed between column 2 and the end of the word "PASSTHRU" will push all following
characters one position to the right. Therefore, any required attributes should occupy column
1 of the first line (just preceding the word "PASSTHRU").
Example:
column: 1 2 3 4 5 6 7 8 9
line 1: @ P A S S T H R U @
line 2: @ P A R T : 1 2 3 4 5
where @ is an attribute.
