system is the System/370 or System/390* system. All workstation types are
negotiated to the 3278 Model 2 workstation when Telnetis in 3270 full-screen
mode. The exceptions to this rule are:
vRemote 3277 workstations are negotiated as a 3277 Model 2
vRemote 3279 workstations are negotiated as a 3279 Model 2
When the Telnetsession is started, your display station is controlled by the remote
system application. Youreceive the same displays and enter data in the same way
that you do for other 3270 devices attached to the remote system.
TN3270—Start TCP/IP Telnet Command
The following optional parameters on the STRTCPTELN or Telnetcommand are
applicable during a 3270 full-screen mode session:
vKeyboard language type (KBDTYPE) (See “TN3270 or TN5250—Specifying
Keyboard and Character Sets”)
vPage up (roll down) key (PAGEUP)
vPage down (roll up) key (PAGEDOWN)
vCursor select key (CSRSLT)
vOutgoing 3270 translation table (TBL3270OUT)
vIncoming 3270 translation table (TBL3270IN)
vTimeout wait for host (INZWAIT)
vNumeric lock keyboard (NUMLCK)
vChange how nulls are handled (NULLS)
Using a Display Station during Telnet 3270 Full-Screen Mode
When using a display station during a Telnet3270 full-screen session, you should
be aware of keyboard and display differences. Other special considerations for
Telnet3270 mode include number of input fields, error messages, and ending a
session.

TN3270 or TN5250—Specifying Keyboard and Character Sets

The keyboard language type you specify for your work station, using the keyboard
language type parameter on the STRTCPTELN command, must be the same as
the keyboard language type parameter of the remotely attached workstation. If you
specify a keyboard language type that does not match, some of the characters are
not displayed as expected.
For a description of different keyboard language types, see the
Local Device
Configuration
book.

5250 and 3270 Keyboards

The placement and function of keys is different on the 5250 keyboard (3196G, 3180
Model 2, or 5291) than on the 3278 keyboard. Differences between these
keyboards are shown in the
3270 Device Emulation Support
book.
Note: For the Telnetclient operating in a 3270 full-screen mode, the 3270 Clear
function defaults to the key sequence Shift-Cmd-Backspace.
