cu

 SYNTAX

 cu [-sspeed] [-lline] [-h] [-o|-e] dir

 cu [-sspeed] [-aacu] [-lline] [-h] [-o|-e] telno

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

 FUNCTION

       cu calls up another system through a modem

       or direct serial connection.  It also controls

       the transmission and reception of data during

       the call.  The options of cu must match

       a line in the /usr/lib/uucp/L-devices file.

       (You'll learn more about this file in the 

       Advanced System Administrator course.)

 cu

 NOTE

       cu is required only on the local system!

       cu is useful for transferring small text

       files only and preferably at low speeds.

       When transferring binary data or large files or

       transferring at high speeds, use uucp!

cu

 SOME OPTIONS

       -s speed  - specifies the transmission speed;

                   1200 baud is the default, minimum 300, max 9600.

         -a acu   - specifies the device name of the ACU.

        -l line   - specifies the device name of the calling-

          out port/line, as defined in the directory /dev.

 Let us use cu for calling another system by 

 using the line /dev/serial, at 1200 baud

 and the telephone number: 8675309!

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 try cu -s1200 -l/dev/serial 8675309

 try cu -s1200 -l/dev/serial 8675309

 try cu 8675309 -s 1200 -l /dev/serial

 try cu 8675309 -s 1200 -l /dev/serial

 You will be helped this time.

 $PROMPT$

FORGET1

 $PROMPT$cu -s1200 -l/dev/serial 8675309 

 $PROMPT$cu 8675309 -s 1200 -l /dev/serial

 Observe the result on the terminal!

 Connected

 At this point you would either a) get a login prompt

 from the remote system, or b) you would have to hit

 <CR> or BREAK to get a prompt, or c) you

 would get nothing because of some line problems.

 After you successfully logged in to the other

 system and you were in the desired directory on the

 remote system, to send a file outfile from

 the local to the remote system use ~%put  outfile!

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 try ~%put outfile

 try ~%put outfile

 You will be helped this time.

 $PROMPT$

FORGET2

 $PROMPT$~%put outfile                 

 Observe the result on the terminal!

 noecho; cat >;;;; echo

 outfile, 2324 characters

 $PROMPT$

 To transfer the file infile from the remote

 system into the local system, use ~%take  infile!

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 try ~%take infile

 try ~%take infile

 You will be helped this time.

 $PROMPT$

FORGET3

 $PROMPT$~%take infile

 Observe the result on the terminal!

 set noecho; jkjkjkljd; cat infile ; echo

 infile, 3457 characters

 $PROMPT$

     To switch from the remote system to the local

     system type:

          ~!<CR>

     To go back from the local system to the 

     remote system enter:

          logout

     To terminate a cu session, while on

     the remote machine, first log off and then enter:

           ~.
