Some explanations on data conversion: To transfer a file that is human-readable you should do it in Ascii mode. Unfortunately the default starting mode is different on different platforms: on ULTRIX, AIX/6000 and all SUN systems, ftp starts in ASCII mode; on HP-UX, DEC OSF/1 and SGI, it starts in binary mode. Ascii is the correct mode to transfer e.g. a TeX source, for example. To transfer compiled programs or similar files you have tobe in binary mode so the transfer can be done on a ``bit by bit'' mode without any change. For example, binary is the correct mode to transfer a dvi file produced by the TeX program. However, contrary to what you might expect, Postscript files (typical suffix .ps) are Ascii format.
