pipe to ftp broken

Since I originally sent this inquiry, I have determined that the problem
is with piping a file to ftp.  I compiled the ftp from the tahoe
collection, and that does the same thing.  I have changed my script to
generate a temporary file and ftp that, but it would be nice if this
problem could be fixed.  -David-

Subject: ftp from pipe broken

I am trying to write a shell script that will accept a file on the
stdin, and ftp it to a file on a remote host.  It requires that the
username and password be specified in the .netrc file.  The necessary
ftp commands are written to a temporary file, and combined with the
stdin by cat.  I find that when I am transferring a certain 1.6MB binary file, 
the transfer aborts prematurely, and it attempts to read the rest of the 
file as ftp commands.  This of course gives me a series of ?Invalid 
command messages, and the resulting file is corrupt.  Any help would be 
appreciated.  -David-

----- start of fileput -----
#! /bin/csh
set host=$1
set file=$2
set mode=$3
set extra=$4
if ("$file" == "" || "$extra" != "") then
    echo usage\: ftpput host file \[mode\] \< local-file
    echo place an entry in \~/.netrc like this:
    echo
    echo machine HOST-NAME login USER-NAME password PASSWORD
    echo
    echo for each host with which you need to communicate
    echo and type \'chmod 600 \~/.netrc\'
    echo the mode can be ascii binary or tenex, ascii is the default
    exit 2
    endif
set MKSTEMP=`mkstemp /tmp/pt`
echo open $host >> $MKSTEMP
echo $mode >> $MKSTEMP
echo put - $file >> $MKSTEMP
/usr/bin/cat $MKSTEMP - | /usr/local/bin/ftp -vd
/bin/rm -f $MKSTEMP
----- start of mkstemp.c -----
/* mktemp.c -- program to generate a unique file name */

#include <stdio.h>
#include <string.h>

char * mktemp ();

main (argc, argv)
int argc;
char * argv [];

{
char filename [256];

if (argc != 2)
    {
    fprintf (stderr, "usage: mktemp prefix\n");
    fprintf (stderr, "returns to stdout a unique file from the ");
    fprintf (stderr, "template: prefixXXXXXX\n");
    exit (2);
    }
strcpy (filename, argv [1]);
strcat (filename, "XXXXXX");
mkstemp (filename);
fprintf (stdout, filename);
exit (0);
}
