Jeg har fundet en kode som virker med bc 5.02 sat til dos projekt.
men har lig problmmer med at forstå den, den er grafisk(semi-grafiks) men vil bare hvae selve kommandoen.
kode:
/****************************************************************************
* *
* Standard Parallel Port (SPP) Debug Tool *
*
http://www.senet.com.au/~cpeacock/pdebug.htm *
* *
* Source Code originally written by Craig Peacock <cpeacock@senet.com.au> *
* *
* Modified by Flavio Poletti <poletti@writeme.com> on July 21, 1998: *
* indentation ;-) *
* extension to DJGPP *
* parallel port addresses retrieval *
* user cannot insert addresses any more *
* mouse is not turned off on redraws *
* some code re-adjusting *
* wait for button release after action *
* *
* THIS PROGRAM COMES WITH NO WARRANTY: IF YOU DECIDE TO USE IT, YOU DO IT *
* AT YOUR OWN RISK. *
* *
* This source code can be freely distributed provided that no modifications *
* are made. Should you have any modifications which you believe would be *
* useful, send them to Craig Peacock <cpeacock@senet.com.au> for inclusion. *
