The X1541 program requires an adapter cable to connect your PC parallel 
printer port (LPT1/LPT2/LPT3) and a commodore disk drive (1541/1581).
*(The Female port pinouts are shown below. The normal cable is Male-Male.)

type "x1541"   for the interface scheme (see above)
type "x1541 ?" for the options list
     options are : "/b" force monochrome mode
                   "/c" force color mode
                   "/LPTn" force I/O from LPT port n (n in range 1..3)

<ALT>     Activate Menu or to dismiss menu and go to file list
          Also used to dismiss status boxes (after COPY)
<ENTER>   Highlight memu or Select menu item
<DOWN>    Highlight menu

<ESC> or  Go back; Highlight previous menu 
<LEFT>or

Cursor keys    Move through menus
<PAGE UP> &    and Move through filelists
<PAGE DN>   


<SPACE>   Select files in filelist for copying

1541-COMMAND Note:     command letter (e.g. N0:Test Format,tt) 
                   Must be capital letter --^


**** Brief command sequence for file copy ********

1. OPEN 1541   <ENTER> to select and highlight Drive# sub-menu
               <ENTER> to select drive number (8-11)
2. OPEN IBM
3. <TAB> to source filelist
4. <SPACE> selects file(s)
5. <ALT> for menu
6. COPY
7. <ALT> to dismiss status box after copy is complete

DE NADA 

Well I forgot to mention it, to make a file with another extension (seq, 
usr, rel (not yet supported)) you should give the correct extension to the
IBM file Eg. *.seq will be transferred as sequential file (seq)

In normal condition 1581 and 1571 have the same mechanism as 1541 but for
lack of documentation I did not implement the fast serial mode feature.

ciao, Leopoldo
