Teklogix 7035, 8255 & 8260 Terminals User Manual
Match Field – the host computer loads data in the format of the expected entry. If
the entered data does not match the expected format, the terminal emits a long beep.
Auto-tab Field – automatically moves the cursor to the next field when the current
field is filled.
Bar code only Field – is filled with data from a bar code reader. Keyboard entries
are not accepted in this type of field.
Serial I/O Field – is filled with data coming from a serial port. Keyboard input is
not accepted in this type of field.
5.4 IBM 5250 Emulation Keys
The following keys allow the Teklogix terminal to better emulate the functions of a
true IBM 5250 terminal.
Note: These keys are active at all times in TESS applications.
5.5 Data Entry
The terminal accepts data until the operator presses a key that sends a transmission
to the host computer. The following actions cause the terminal to transmit:
• Pressing a function key or the <ENTER> key (which is considered to be
<F0>) causes the terminal to transmit.
• Completing data entry into a “transmit on entry” field also causes the
terminal to transmit.
