@Qbix: I have to understand the recent changes first 😢 @joe_pool_is: Move the one and only serialport.h from the zip to dosbox\include.

No, that is the real one. ds.h was supposed to be named directserial_win32.h 🙄

Oops... there is actually too many files. Delete: directserial.cpp directserial_win32.h dserialwin32.h The first one is a failed attempt to use a serial port library. The others are there because VC made me angry. I will fix the zip.

The latest version is in DirectSerial patch Since I used the february CVS as my base, a diff file would cause the same problem, and I didn't make one. I put all files I modified in a folder.

If an application exists that directly reads those values it could be closer to work. A Gates's dos booted inside dosbox now feels that there must be a comport around somewhere (mode …

It is now in the Sourceforge dosbox patches section. I Hope i did everything right. I also added some more changes.

Ok, until i figure out how to make patches and upload things to Sourceforge I will attach it here. Things tested with this code: - Microsoft mouse driver (with microsoft mouse, of course :-), using a disk image - An old tool I checked computers for brown-out serial ports a century ago (internal …

Hello, First, nice work, that Dosbox. When i got it, i played all of Dune2 again. With sound. I wanted to tell you that i improved the direct serial port code.
