IBM 3270 Emulation
Network Virtual Terminal Mode
Network Virtual Terminal (NVT) mode allows the operator to communicate with a
network gateway (in ASCII) for routing, logon etc, before the full IBM terminal
emulation protocol is established. NVT mode is indicated by the ? symbol in the
status line along the bottom of the display.
NVT mode displays an unformatted screen for data entry, allowing most of the
keyboard functionality for local editing. However, when the Enter key is pressed, the
line that the cursor is positioned on will be sent over Telnet as an ASCII string with
CR/LF terminators. The cursor will then be positioned at the start of the next line.
ASCII data received over Telnet will also be displayed at the current cursor position. A
CR character will be actioned as a 'new line' character, causing the cursor to move to
the start of the next line, scrolling the display if necessary. Once the appropriate details
have been entered to establish an IBM host session (which may be automatic), the
screen is cleared and switched into full IBM 3270 terminal emulation mode, as
indicated by the symbol in the status line.
Host Selection
Up to four host connections can be specified using the Connection Wizard. When two
or more hosts have been configured you can use the following keyboard commands to
launch or switch between each session:
Alt + S Switch to or launch the next session if not already launched. Note that this
will cycle through hosts 1 to 4 (if configured) in order.
Ctrl + S Switch to previous session. Note that the session must already be launched
as this will not launch a session.
Ctrl + X Exits all sessions. A warning message box will ask if you really want to
exit. Click Yes to exit all.
IBM 3287-1 Printer Support
TN3287 printing is supported by setting the IBM 3270 Model option in the IBM
3270 Settings dialog box to 3287-1. When a new Telnet connection is made, the
display will change to show a message box which will indicate the current printer
status.
When printing commences a Print Abort box will be displayed enabling you to cancel
the print job. Note that this will stop print data being sent but will not disconnect you
from the host.
