Is there any way to get the mouse to work in LemEdit under Dosbox? I'm unfortunately stuck running Windows 7 (I'd rather not have to boot up my clunky old XP machine in order to edit Lemmings levels), and Microsoft had the absolutely brilliant idea to nuke DOS program support somewhere between here and XP.

Google turns up a cached version of a thread on camanis.net (which seems to be down) that says:

As for LemEdit, the problem is that you need a mouse hooked up into your COM1 port. Basically, you can't use USB or PS/2 mice unless you have a PS/2 to serial converter... or something like that...

And considering I haven't owned a serial mouse in at least a decade, that's a bit of a problem. I tried looking up ways to emulate a serial mouse in Dosbox, but I just get some things about mouse drivers in Linux and modem emulation and other things that don't really help. I read something about a patched version of LemEdit that fixed the serial mouse problem, but it looks like it was only hosted on camanis.net, and that's down. Does anyone here have it? Or is there a way to get Dosbox to trick LemEdit into thinking there's a serial mouse in COM1, if that's what's necessary to get it to work?
