Wow! Fantastic hints! This helps with a number of issues. My problem at the moment is that i have gotten the com ports to work, but only as root. I'm not talking about for brltty and speakup, which transition over, but for other uses. I am using debian, and my ttyX are set for root and dialout; since I am a member of dialout this isn't a problem in linux. However, I have tried changing the permissions for these ports with chmod to 666 or even 1777 (something I don't probably want on a regular basis) with no change to my serial port access within dosemu. Any help on this would be appreciated. However, I can use the3 editor and wp5.1 and the floppy drive works, and i am hoping to figure out why megadots isn't working; might possibley be a memory problem or could be something more complex. Thanks for that excellent post!!!
