ftp file transfer with garbage

The following string appeared at the beginning of a text file:

1 ˆ ‚+Â ‚!‚ €5R ÅIaRóÌ$2EOÉ     HPÔ=&|„Ã<r

For a long time I've been using one script in DOS with ftp commands to send text files from windows98 to Unix.
But yesterday and today the received file showed OK unless those strange characters.

What can be causing this addition of characters ?
Help if you know please.

NO. please read man-pages.
bin is the only posibility to transfer a file as is, without any, more or less sophisticated (mainly wrong), conversion.

Network might also be a problem, but is unusual, 'cause ftp is a TCP protocol, which should check for network errors.
see bin and ascii command of ftp

the mode in use is ascii.
The running script (a batch file) is something like this:

open 999.99.99.99
user ??? ???
user ??? ???
cd ???
mput \\server\???\mainname.*

is it ftp from DOS to UNIX?
I suggest to use bin always.
bin mode will replace every end of line with ^m and the like for text files. Use ascii for text files. Make sure they ARE text files, wordpad docs and word files etc are binary files.  Edit and notepad should display the files with no funny chars if the file is truly text (so will "type" from cmdline).

You could have had a noisy line, or an error on one of the file systems, or some other one time error. Try a few times and see if it happens all the time or not.

It can also be a network error, which you cannot help. Especially if everything worked smoothly before and this error is in there for only one time... Networks get stressed once every while.

I know this is obvious but have you checked the file that you are ftp'ing to make sure that the crap you see whn copting the file isn't in the original file due to some form of corruption at some stage on the source system?

The cause is not yet found. Maybe a firewall had helped it.
