A SETMODE function 144 procedure also returns a value indicating the IBM device
type. The IBM device type code returned depends on which IBM terminal emulation is
selected for the window during Telnet terminal type negotiation. If the -k option is
selected, a value of 2 is returned, indicating that the terminal is not a 3277 or 3276
terminal.
