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
.
Communication Port Settings
Ensure that the device you connect communicates using these settings:
H Data rate set to 9.6 kbps.
H Character length set to 8.
H Parity set to None.
H Stop Bits set to 1.
