Using the Asynchronous Terminal
Interface
2
User Interface Access
You can communicate with the Hotwire 7975 Standalone Termination Unit with an
asynchronous terminal interface (ATI) using one of the following methods:
H
Direct connection through the COM port.
H
Using an external modem through the COM port.
H
Telnet session through the Embedded Operations Channel (EOC).
NOTE:
Only one asynchronous terminal interface session can be active at a time,
and another user’s session cannot be forced to end. To automatically log out
a user due to inactivity, enable the Inactivity Timeout option (see Table A-5,
Telnet Sessions Options
, in Appendix A,
Configuration Option Tables).
Security can limit ATI access several ways. To limit user access or set up login
IDs, refer to
Chapter 7,
Security
.
