Introducing the TN3270 Emulation Program
Overview
• Issue the file transfer commands by using the TN3270 emulation
program's menus and dialog boxes or transfer files from the HP-UX
command prompt. For step-by-step instructions, see Chapter 5,
“Transferring Files.”
Background Operation
You can use a command-line operation to run the character-based
TN3270 emulation program in the background. In this case, you cannot
directly view the 3270 display or use the keyboard, but you can run
HLLAPI applications or command-line file transfers that access 3270
display sessions. For more information about running the TN3270
emulation program in the background, see Chapter 3, “Getting Started
with 3270 Emulation.”
Temporary Exit from TN3270 Emulation
While using the TN3270 emulation program, you can perform a
temporary exit to one of the HP-UX shells while leaving the TN3270
emulation program running. Use the temporary exit, for example, to list
the contents of a directory or to run a HLLAPI application or a
command-line file transfer. For more information about the temporary
exit feature, see “Temporary Exit from 3270 Emulation”.
Motif The TEMPEXIT keystroke is not supported in the Motif 3270 emulation
program. Instead, you move to a new terminal window using the mouse
as usual.
