DKCU ( 1C ) 
DKCU
NAME
dkcu – call another host
SYNOPSIS
dkcu
[ – ] [ – ] [ – ] [ – ] [ – destination
DESCRIPTION
dkcu
dials another UNIX System, a terminal, or possibly a non-UNIX System.  It
manages an interactive conversation with possible transfers of
ASCII
files.
It places a call to the destination host or terminal on the data switch network.
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 - 
v
destination.rl.vt’) and the user should be authorized [see
authorize(1M)] on the destination host.
x
Requests that XON/XOFF output flow control be done locally; otherwise,
XON/XOFF characters are passed through to the destination.
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.
˜ !
Escape to an interactive shell on the local system.
˜ !
cmd . . .
Run cmd on the local system (via ’sh – c’).
˜ $
cmd . . .
Run cmd locally and send its output as standard input to the
remote system for execution.
˜ %take
from to ] Copy 
file from (on the remote system) to file to on the local
system. If to is omitted, the from argument is used in both
places.
