Verify TN3270 Keyboard Maps
A keyboard map assigns the functions on the IBM TN3270 keyboards to keys or key
sequences on ASCII terminals. The default TN3270 keyboard maps are sufficient for most
applications.
Use the VT100 default keyboard map for a VT100 terminal device and the VT220 default
keyboard map for all other terminal devices.
