Several options are supported by dkcu:
Several options are supported by dkcu:
–
s
Suppresses the "Circuit Open" and other non-error messages.
–
f
Forces a dkcu even if the user came in as a remote executor.
–
d
Used to get tracing and diagnostic output.
–
v
Local environment variables may be passed from the calling host to the desti-
nation host by listing them in the local environment variable DKEXPORT
(such as, ’DKEXPORT=TERM,LINES,COLUMNS’). When using this
option, the destination should be appended by ’rl’ and ’vt’ flags (such as,
’dkcu -

(such as, ’DKEXPORT=TERM,LINES,COLUMNS’). When using this

After making the connection, dkcu runs as two processes: the transmit process
reads data from standard input and, except for lines beginning with ’˜’, passes it to
the remote system. The receive process accepts data from the remote system and,
except for lines beginning with ’˜’, passes it to standard output. Lines beginning
with ’˜’ have special meanings.

The transmit process interprets the following:

Terminate the conversation. If the program on the remote
host isn’t reading input, typing the QUIT character twice,
rapidly, will break the connection.
