system is the System/370 or System/390* system. All workstation types are
negotiated to the 3278 Model 2 workstation when Telnet is in 3270 full-screen
mode. The exceptions to this rule are:
v Remote 3277 workstations are negotiated as a 3277 Model 2
v Remote 3279 workstations are negotiated as a 3279 Model 2
When the Telnet session is started, your display station is controlled by the remote
system application. You receive 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 Telnet command are
applicable during a 3270 full-screen mode session:
v Keyboard language type (KBDTYPE) (See “TN3270 or TN5250—Specifying
Keyboard and Character Sets”)
v Page up (roll down) key (PAGEUP)
v Page down (roll up) key (PAGEDOWN)
v Cursor select key (CSRSLT)
v Outgoing 3270 translation table (TBL3270OUT)
v Incoming 3270 translation table (TBL3270IN)
v Timeout wait for host (INZWAIT)
v Numeric lock keyboard (NUMLCK)
v Change how nulls are handled (NULLS)
Using a Display Station during Telnet 3270 Full-Screen Mode
When using a display station during a Telnet 3270 full-screen session, you should
be aware of keyboard and display differences. Other special considerations for
Telnet 3270 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 Telnet client operating in a 3270 full-screen mode, the 3270 Clear
function defaults to the key sequence Shift-Cmd-Backspace.
