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:

where @ is an attribute.

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

1 2 ... 295 296 297 298 299 300 301 302 303 304 305 ... 435 436
