Nortel Networks 3395A manual Using Hot Keys, Scroll Lower key, Status Key

TN3270 Sessions

Once the terminal server establishes a session with the IBM host, the terminal server software begin IBM 3270 terminal emulation. To check the functions of keys during a session, use the <CTRL><X> key sequence. This key sequence displays a table similar to the SHOW PORT KEYMAP display. Tables 4-1, 4-2, and 4-3 at the end of this chapter show 3270 keyboard functions and the corresponding keys on terminal types that are included in the software.

Note: If you are using a personal computer (PC) and running terminal emulation software, this software may not match every IBM display station key to the corresponding key on your keyboard.

Using Hot Keys

Most terminals have screens that display twenty-four lines, while IBM Model 5 stations display twenty- seven lines plus a status line, and IBM Model 2 stations display twenty-four lines plus a status line. To view the extra display lines and the status lines, you use hot keys. When you press a hot key, the terminal displays the hidden display lines or the status line. When you press it again, the hidden lines disappear.

The Scroll Lower key

To view the three extra display lines on an IBM Model 5 display station screen, use the Scroll Lower function key. The Scroll Lower key changes the display from the top twenty-four lines (1-24) to the bottom twenty-four lines (4-27). Using the Scroll Lower key again returns the display to lines 1-24. The Scroll Lower keys for the predefined keyboard maps are these:

VT100/102 and ANSI ESC L

VT220/7-bit<CTRL><O>

VT220/8-bit<CTRL><O>

The network manager can change the predefined key sequence, so the Scroll Lower key sequence on your terminal may be different.

The Status Key

To view the status line on an IBM Model 2 or Model 5 display station, use the Status key. (On Model 5 this is the twenty-eighth line of the screen; on Model 2 this is the twenty-fifth line of the screen.) To view this line, use the Status key that applies to your terminal's keyboard map:

VT100/102 and ANSI ESC ?

VT220/7-bit<CTRL><W>

VT220/8-bit<CTRL><W>

The network manager can change the predefined key sequence, so the Status key sequence on your terminal may be different.
