Field Overhead
This parameter contains the maximum number of characters allowed between two
fixed fields which still allows the 9150 to join them into one field.
Sometimes the 9150 will join two adjacent fixed fields and then send them as one
field. This reduces the overhead on the radio link.
For example, if two fields were 4 characters apart and this parameter was ‘5’, then
these fields would be joined into one.
Command Region
This parameter defines a region of the host screen which the 9150 will examine for
the presence of reserved commands.
The four numbers in the Command Region textboxes represent the row and column
addresses of the upper left corner and the lower right corner of the command region.
The first textbox of each pair contains the row number; the second contains the
column number. The range of row values is 0 to 24; column values are 0 to 80.
To define the last two lines of the host screen as the command region, for example,
enter the values 23, 1 and 24, 80.
Currently, the only command supported is ALARM (refer to page 151 for details on
this command). When the word “ALARM” is placed anywhere within the command
region, the 9150 will send a TESS beep command to the terminal.
