Interactive Terminal Interface
A Guardian TN3270 Server window assigned to the interactive terminal interface (ITI)
protocol is used to run the Tandem Advanced Command Language (TACL). With a
TACL process running on the subdevice, the terminal operates in an interactive
environment. As a result, you can initiate any kind of application process (such as EDIT
and FUP) allowed on a standard interactive device.
You can configure the Guardian TN3270 Server to run in CRT or ITI mode with a
SETMODE 8 call. See Section 5, CRT Communication Protocol
for more information
about running the Guardian TN3270 Server in CRT mode. By default, the Guardian
TN3270 Server uses ITI mode.
