CU(1C) UNIX Programmer's Manual CU(1C)

== NAME ==
cu - call UNIX

== SYNOPSIS ==
cu telno [ -t ] [ -s speed ] [ -a acu ] [ -l line ]

== DESCRIPTION ==
_C_u calls up another UNIX system, a terminal, or possibly a
non-UNIX system. It manages an interactive conversation
with possible transfers of text files. _T_e_l_n_o is the tele-
phone number, with minus signs at appropriate places for
delays. The -t flag is used to dial out to a terminal.
_S_p_e_e_d gives the transmission speed (110, 134, 150, 300,
1200); 300 is the default value.

The -a and -l values may be used to specify pathnames for
the ACU and communications line devices. They can be used
to override the following built-in choices:

-a /dev/cua0 -l /dev/cul0

After making the connection, _c_u runs as two processes: the
_s_e_n_d process reads the standard input and passes most of it
to the remote system; the _r_e_c_e_i_v_e process reads from the
remote system and passes most data to the standard output.
Lines beginning with `~' have special meanings.

The _s_e_n_d process interprets the following:

~. terminate the conversation.
~EOT terminate the conversation

~<file send the contents of _f_i_l_e to the remote
system, as though typed at the terminal.

~! invoke an interactive shell on the local
system.

~!cmd ... run the command on the local system (via
sh -c).

~$cmd ... run the command locally and send its out-
put to the remote system.

~%take from [to] copy file `from' (on the remote system) to
file `to' on the local system. If `to' is
omitted, the `from' name is used both
places.

~%put from [to] copy file `from' (on local system) to file
`to' on remote system. If `to' is omit-
ted, the `from' name is used both places.
~~... send the line `~...'.

The _r_e_c_e_i_v_e process handles output diversions of the follow-
ing form:

~>[>][:]file
zero or more lines to be written to file
~>

In any case, output is diverted (or appended, if `>>' used)
to the file. If `:' is used, the diversion is _s_i_l_e_n_t, i.e.,
it is written only to the file. If `:' is omitted, output
is written both to the file and to the standard output. The
trailing `~>' terminates the diversion.

The use of ~%put requires _s_t_t_y and _c_a_t on the remote side.
It also requires that the current erase and kill characters
on the remote system be identical to the current ones on the
local system. Backslashes are inserted at appropriate
places.

The use of ~%take requires the existence of _e_c_h_o and _t_e_e on
the remote system. Also, stty tabs mode is required on the
remote system if tabs are to be copied without expansion.

== FILES ==
/dev/cua0
/dev/cul0
/dev/null

== SEE ALSO ==
[[32v 4m dn|dn(4)]], [[32v 4m tty|tty(4)]]

== DIAGNOSTICS ==
Exit code is zero for normal exit, nonzero (various values)
otherwise.

== BUGS ==
The syntax is unique.
