TN3270 Sessions
893-386-B
4-1
You can establish sessions over the LAN with an IBM host through the terminal server if the host has a
Telnet server that supports the TN3270 protocol.  When you log on to the IBM host, the terminal server
software redefines the functions of the keys on your terminal's keyboard to emulate those of an IBM 3270
Model 5 or Model 2 display station.  This chapter includes these topics:
Checking the TN3270 characteristics at your port
Establishing a TN3270 session with an IBM host
Using hot keys
Keyboard maps
Checking the TN3270 Characteristics at Your Port
Before you attempt to establish a connection with an IBM host, check the settings of the TN3270
characteristics at your port with the SHOW PORT TELNET CHARACTERISTICS command.  This
display shows the following information:
The device your terminal emulates once you log on to the IBM host.  The terminal server software
includes the VT100, VT220-7, VT220-8, and ANSI device types, but the network manager at your site
may have created other types.
The translation table for the language your port uses during the TN3270 session.
Figure 4-1 shows a SHOW PORT TELNET CHARACTERISTICS display with typical settings for the
TN3270 characteristics.  The display at your port may be different.

In Figure 4-1, the TN3270 translation table in column one is set to USENGLSH, which is the default
setting for this characteristic.  The TN3270 device in column two is set to VT220-7, but the setting at your
