Security Information

Access to the BMC via terminal mode is governed by the proper setup of usernames and password
via the SMU. A session must be established with the BMC prior to accepting any terminal mode
commands. A limited selection of text commands and binary hex-ASCII commands that are
assigned the lowest IPMI privilege level are available prior to session establishment with the BMC.
Since the terminal mode password is sent via clear text, it is highly desirable that the terminal mode
session takes place in a secure location over a secure link, preferably via a direct connection.
Connection via a modem is supported but not recommended.

Terminal Mode Commands

Input Restrictions
Terminal mode messages are bound by the restrictions listed in the following subsections.
Syntax
Terminal mode messages follow the general syntax below:
[<message data>]<newline sequence>
Each terminal mode message must be preceded with the left bracket "start" character and must be
ended with a right bracket "stop" character and the appropriate input newline sequence.
No input characters are accepted until the start character has been received.
Terminal mode text commands are case sensitive, but hex-ASCII commands can either use upper or
lower case letters for ASCII representations of hex digits.
Command Length
Terminal mode messages are limited to a maximum length of a 122 characters. This includes the
left and right brackets, but not control characters.
Character Support
Terminal mode messages are allowed to be composed of standard printable ASCII characters. All
other characters are treated as illegal characters.
Special Character Handling - <ESC> character
The <ESC> character can be used to delete an entire message prior to submission to the BMC for
processing. If line editing is enabled, and the <ESC> key is followed by an input newline
