Why do you think this modem problem has something to do with directserial, and that the actual problem is in directserial? I never thought it had anythiong to do with a mouse except you mentioned that a rewrite was coming out for all the serial ports. Are you saying there won't be any improvements …

So after mailing me often and moving to the forum, when I didn't answer within the hour, you are now spamming the forum ? DOSBox is for games. Fixing autocad is low priority. I'm not trying to spam. I just wondered when the serial port fixes might be coming out since you mentioned they are to be …

The modem emulation is flagged for rewrite (as other serial port units). Try the nullmodem too, it has some special settings for BBS purposes and might perform better. Do you know approximately when the serial ports will be rewritten? I'm having a rough time with a serial mouse in autocad 10. Very …

This 1986 game supports a serial mouse, but not the PS/2-style mouse that DOSBox emulates. I think there is a way to use directserial and a real serial mouse, but not sure if it will work. It works. You have to connect serial mouse to your com after windows has completely booted, so that it won't …

I tried setting dosbox.conf to serial1=dummy with the windows mouse disabled but the mouse still is slack in dosbox. If I move the mouse up and down about once a second the cursor is actually down when my mouse is up and vice versa.

I tried disabling the windows mouse and connecting a serial mouse to com1 with the serial mouse driver in autoexec.bat in dosbox.conf. It works but even a little worse than the windows mouse. I'm still using serial1 as directserial in doscox.conf. Should that be set to dummy or something else?

Just running NortonCommander in Dosbox still gives me inaccurate mouse response so I don't think this has anything to do with the autocad drivers.

I tried reducing the cycles and increasing the vga skip but niether helped the mouse sluggishness. I should also mention that even just running norton commander in dosbox results in an inaccurate mouse response.

I tried the mouse disable trick and that didn't help either.

I tried what hal said and it doesn't improve the mouse response

Are you overloading your CPU maybe? (cycles too high) I turned of the fifo buffers like you said, rebooted and tried auto, fixed and max for the cycles but none made any difference to the mouse, at least not noticeably. Someon told me that there's likley a regulator in the emulator to keep timing …

I'm using a gyration mouse with a usb connection. Autocad 10 has two choices for mice: mouse systems 3 button/ms or logitech 3 button. I'm using the mouse systems driver in autocad. The delay is worse when I don't use the direct serial setting in dosbox conf.

I'm running acad 10 dos in dosbox and everything is fine except for the mouse is sluggish sort of like the cursor is on the end of a long thin rubber stick. It overshoots the intended cursor position making it difficult to pick entities. Anyone that can help? I have the settings in dosbox.conf as …

Oh ya, acad 10 & 12 have lots of tablets to choose from so that's why I thought any results you may have may help.

I'm runnin g acad dos 10 and 12 with dosbox and everything works just fine except for the mouse is sluggish. It overshoots the intended cursor destination sort of like the cursor was on the end of a long thin rubber stick making it difficult to pick entities. I'm using serial direct in the dosbox. …
