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 preceding the
field with a special character.
If this character precedes a fixed field, the data will be sent to the mobile computer's serial
port. If it precedes an entry field, the field accepts data from the mobile computer's serial
port.
The range for this parameter – 0 to 255 – 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 applica-
tion screen (see also Entry Line). A value up to 24 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 pre-
ceding the field with a special character.
The range for this parameter – 0 to 255 – 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 mobile computer includes an entry field that would normally be out of
bounds. Some Psion Teklogix mobile computers only display the upper-left corner of the ap-
plication screen because of their smaller display size.
