TELNET> SHOW PARAMETERS
Will flush output when sending interrupt characters
Won't send interrupt characters in urgent mode
Will map carriage return on output
Won't recognize certain control characters

TELNET>
Displays the parameter settings for the active session,
revealing the following information:
o Automatic flushing (AUTOFLUSH) of output is enabled.
o Sending of interrupt characters in urgent mode (AUTOSYNCH)
is disabled.
o Mapping of received carriage returns (CRMOD) is enabled.
o Mapping of carriage returns as Return LP on output (CRLF) is
disabled.
o Interpretation of control characters (LOCAL_CHARS) is
enabled. The remote host does not recognize certain control
characters; therefore, the local host interprets them.
o Display of option negotiations (OPTIONS_VIEW) between the
local and remote hosts is disabled.
o The display or printing of data in hexadecimal (DEBUG) is
disabled. Therefore, TELNET displays the data in readable
text only.
o The control characters are interpreted as listed.
