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.)

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
