I give up. I can't get DosBox to write to the parallel port. I will try VirtualBox next. Bye, Joe.

wengier failed to document the options for the parallel port other than true or false. Do you think that he meant the same options for the serial port are applicable for the parallel port? I will try them.

Well, so much for svn... I connected a breakout box to the motherboards parallel port on back. I booted MS-DOS and ran a test program which wrote to the parallel port. The breakout box displayed the data. I booted win 7 and ran the test program thru DOSBOX SVN, after setting the LPT's and PRN to …

Thanks for your help. I'm going to try the SVN-LFN by Wengier. It supports LPT1.

You mention an alternate build. Is there a .cpp file available for LPT1?

can dosbox allow access to the parallel port (0278h)?

Apparently just working in MsDos using an int10h function10h will allow me to set the bkg palette color to whatever, but only in regular video modes(640x480) and not in int10h function4f Vesa modes (1280x1024). And so the problem is not with DosBox running in Windows XP but with my program itself. I …

Can dosbox be started with a white screen?

Oops. Removed the -0.74 from the name and all is well. Thank you for the help. Joey.

I have a copy of DOSBOX.exe in each folder, and click on that icon. There is no icon on the desktop (shortcut). (I forgot to mention I am using Win XP). I also have a dosbox-0.74.conf file in each folder with a different [autoexec]. Joey.

I am referring to the file in doc's and set's\me\local\applications. I copied that file to each directory of interest, modified the [autoexec] lines to pertain to that application, and ran DOSBOX. It still went back to doc's and set's etc. no matter which directory I was in. Joey.

Hoe can I relocate or have a config file in the directory that contains the DOSBOX.exe file and target file, so as to have a unique config file for each DOSBOX/target application in different folders or partitions.
