If you ftp UNIX->UNIX it is not a problem. Going from Windows to unix is.

Unix filesystems have no concept of a "binary" file, windows filesystems do. Windows thinks carriage control files are "TEXT"
It ends a text file with ascii 26. Binary files in windows are supposed not to have carriage control, so all characters are valid ascii 0 - 255.

The standard C I/O library considers ASCII 0 as end of string, except when doing fread or fwrite calls (read & write in UNIX)

If you are ftp-ing media files and compiled Oracle forms, then use BIN.

Do you get spurious "^M" characters in the file on the UNIX side when sent from windows? Do you have corrupted compiled Oracle forms?

ASCII-XFR(1)							Linux Users Manual						      ASCII-XFR(1)

NAME
ascii-xfr - upload/download files using the ASCII protocol SYNOPSIS
ascii-xfr -s|-r [-ednv] [-l linedelay] [-c characterdelay] filename DESCRIPTION
Ascii-xfr Transfers files in ASCII mode. This means no flow control, no checksumming and no file-name negotiation. It should only be used if the remote system doesn't understand anything else. The ASCII protocol transfers files line-by-line. The EOL (End-Of-Line) character is transmitted as CRLF. When receiving, the CR character is stripped from the incoming file. The Control-Z (ASCII 26) character signals End-Of-File, if option -e is specified (unless you change it to Control-D (ASCII 4) with -d). Ascii-xfr reads from stdin when receiving, and sends data on stdout when sending. Some form of input or output redirection to the modem device is thus needed when downloading or uploading, respectively. OPTIONS
-s Send a file. -r Receive a file. One of -s or -r must be present. -e Send the End-Of-File character (Control-Z, ASCII 26 by default) when uploading has finished. -d Use the Control-D (ASCII 4) as End-Of-File character. -n Do not translate CR to CRLF and vice versa. -v Verbose: show transfer statistics on the stderr output. -l milliseconds When transmitting, pause for this delay after each line. -c milliseconds When transmitting, pause for this delay after each character. file Name of the file to send or receive. When receiving, any existing file by this name will be truncated. USAGE WITH MINICOM
If you want to call this program from minicom(1), start minicom and go to the Options menu. Select File transfer protocols. Add the fol- lowing lines, for example as protocols I and J. I Ascii /usr/bin/ascii-xfr -sv Y U N Y J Ascii /usr/bin/ascii-xfr -rv Y D N Y AUTHOR
