3270 Functions

Attention

Interrupts the host application program. Not all host Telnet programs support the Attention key.


Clear

When you first log on, your host connection is in implicit state, meaning that there is only a single partition. In implicit state, Clear erases all data in the partition. When there are multiple partitions, Clear erases all data in all partitions, and returns the emulator to implicit state. When there are multiple partitions, use the Clear Partition function to clear only the current partition. Most host applications use only a single partition.


Clear Partition

Erases all data in the current partition.


Cursor Blink

Changes the blink rate of the cursor, cycling through two options (Blinking Disabled and Windows System).


Cursor Select

Simulates a light pen select in the field containing the cursor. Sets or clears the attribute indicating that a field has been modified. You can use the right mouse button in selectable terminal fields to perform a cursor select; in this way, the mouse can be used to simulate a light pen.


Delete Character

Deletes the character the cursor is on.


Delete Word

Deletes one word of text from an input field.


Duplicate

Inserts a dup character into the buffer. The cursor moves to the first position of the next unprotected field if the screen is formatted, or to row 1, column 1, if the screen is unformatted.


EraseEOF

Erases all data from the cursor location to the end of the current field.


Erase Input

Erases all unprotected fields in the current partition.


Field Delimit

Toggles IBM standard and extended field delimiters on or off during a host session. Toggling can be useful for troubleshooting.


Field Mark

Inserts a field mark character.


Key Click

Toggles the keyclick on or off. When this function is on, the PC emits a low-pitched sound in numeric fields, a high-pitched sound in alphabetic fields, and no sound in protected fields.


Pan Left

Moves the portion of the current partition visible on the screen so that a different part of the partition is visible. The distance panned is determined by the host upon establishment of the partition. If Host Integrator can display the entire partition on the terminal screen, this function has no effect.


Pan Right

Moves the visible portion of the current partition so that a different part of the partition is visible. The distance panned is determined by the host upon establishment of the partition. If Host Integrator can display the entire partition on the terminal screen, this function has no effect.


Partition Jump

Moves the cursor to the next partition. Continuing to use this function cycles you through all available partitions.


Scroll Down

Moves the visible portion of the current partition so that a different part of the partition is visible. The distance scrolled is determined by the host upon establishment of the partition.


Scroll Up
