Serial I/O
Serial I/O fields are special entry and fixed fields that accept input from and output
to a serial port. The application program distinguishes this field as Serial I/O by pre-
ceding the field with a special character.
If this character precedes a fixed field, the data will be sent to the terminal’s serial
port. If it precedes an entry field, the field accepts data from the terminal’s
serial port.
The range for this parameter – 0 to 127 – represents the decimal values of ASCII
characters. A value of 0 (zero) disables this feature.
Print Line
This parameter allows you to enter the starting line number of the print page in the
application screen. A value of 1 causes the display page to be printed; a value of 0
(zero) disables this feature.
Print Form Length
This parameter sets the printer’s form length in lines. The range is 0 to 24.
Barcode
Barcode-input-only fields are special entry fields that only accept input from a bar
code reader. The application program distinguishes an entry field as barcode-input-
only by preceding the field with a special character.
The range for this parameter – 0 to 127 – represents the decimal values of ASCII
characters. A value of 0 (zero) disables this feature.
Entry Line
This parameter contains the number of the first line displayed if there is no entry
field in the upper-left portion of the screen, and if an entry field is at or below
this line.
The Entry Line parameter allows an automatic offset within the host screen, so that
the area displayed by the terminal includes an entry field that would normally be out
of bounds. Normally, Teklogix terminals only display the upper-left corner of the
application screen because of their smaller display size.
